EXPERIENCE OF PARAMETRIC IDENTIFICATION OF THE SPICE[1]MODEL OF A TTL MICROCIRCUIT

Simulation of electronic circuits using specialized CADs is an integral part of the electronics design flow. However, models provided by manufacturers often represent the behavior of a component in a very simplistic manner, and models that reproduce it over a temperature range are usually not available to developers. To increase the accuracy of simulation results, users can refine the parameters of the original model, as well as add dependencies of the parameters on temperature. In the article, the authors have considered the structure of the original model of the integrated circuit SN74HC02 manufactured by Texas Instruments. Its shortcomings, which lead to significant differences between the simulation results and the experiment, have been considered too. The authors have given experience in refining the model parameters and adding temperature dependences of the parameters to reduce the error in the simulation results. The authors have concluded that the changes made make it possible to decrease the error in the simulation results, however, to further improve the accuracy, a significant change in the model structure is required.

DESIGN OF A FIBER OPTICAL MICRODISPOSITION CONVERTER ELECTRONIC DEVICE

This paper presents a description of the design of a fiber­optic pressure sensor and the principle of operation. The principle of operation of fiber optic pressure sensors is as follows. From the radiation source, the light flux is directed along the supplying optical fibers towards the membrane at an angle, the value of which is selected from the condition of ensuring the maximum conversion sensitivity and the modulation depth of the optical signal. Under the action of controlled pressure, the membrane bends, and in the central part the gap between the membrane and the beveled ends of the optical fibers will be less than the initial value of X0 . As a result, the reflectivity for electromagnetic waves in the area of the beveled ends of the optical fibers changes, and the intensity of the light flux reflected at an angle from this area, which carries information about the measured pressure and arrives through the outgoing optical fibers to the radiation receiver, changes accordingly. A new design of the fiber­optic pressure sensor has been developed. The calculation of the optical system of the fiber­optic pressure sensor, which consists in determining a number of design parameters of the fiber­optic microdisplacement transducer. Mathematical modeling was carried out in the MathCAD environment. Based on the results of mathematical modeling, a new design solution for a fiber­optic microdisplacement transducer is proposed, in which the input and output optical fibers are cut and located at a design angle. The function of converting the VOTMP has been determined.

RGB histograms are sensitive to the color content of the image and its brightness. They are affected by changes in the weather, the illumination of the place under consideration, and the appearance of random objects that are not the purpose of the study. In this regard, the question arises about the possibility of using the method of processing histograms as a method for detecting objects and determining the accuracy of their presence in the image. A section of the river that has an island and is bounded by the banks is chosen as the research site. The probability of detecting ships on a series of satellite images is considered. A confidence interval is found for values that correctly indicate the location of objects. The available images are not pre­processed. There are images containing dense clouds. The obtained RGB values of the histograms are compared with the values obtained from the image in which the vessels are not present. RGB histograms are evaluated using the “slope angle” method.

PROBABLE MODEL OF ENCODED TEXTS DIFFERENCE

In the article a probable model of the difference between gammed encoded texts is constructed. Such a model is necessary to solve the problem of detecting cryptograms of the same modular gamming. The goal is to check two competing statistical hypotheses regarding the difference between the encoded texts. In order to create such criteria in the best way, it is necessary to describe competing hypotheses. If cryptograms are re­encoded with the same gamma, then the difference of these texts can be modeled by an unequal polynomial scheme. The article presents the parameters of such a polynomial scheme. It turned out that the probability of a “zero outcome” of the scheme is almost constant for all languages, and this value was estimated. If the cryptograms are re­encoded with different gammas, then the difference of these texts is modeled by an equally probable polynomial scheme.

Keywords: summirovanii texts, it is the same summirovanii, the difference between the texts, the polynomial scheme.

THE MULTILAYER CONTACTS RESISTANCE EFFECT ON THE ABSORBING ELEMENT PARAMETERS

A multilayer film contact model is constructed and a technique is proposed for assessing the contacts resistance effect on the film absorbing elements attenuation and input resistance for waveguide, coaxial, and microstrip attenuators with planar, end, and covering contacts. As an example, the size 0603 a thin­film resistor multilayer contact was studied, the normalized currents distribution in the layers along the contact length at different etching angles of the conductive film is shown. A decrease in the etching angle extends the current transition region from the conducting layers to the resistive film, improves the resistive film thermal mode, and complicates it for the conductive film. A weak dependence of the contact resistance value (less than 3%) and the released power (less than 8%) on the etching angle was revealed when it changed within 45­90°. The various technological designs contact resistances influence valuations are obtained on the absorbing elements of a size of 2 × 2 × 0,5 mm input resistance and attenuation for surface mounting. This effect does not exceed 1% in attenuation for absorbing elements of small attenuation (of 1 dB or less) and 0,3% in input impedance, but for multistage attenuators with many absorbing elements it becomes decisive.

MODEL SAMPLE GENERATION ACCORDING TO GOMPERTZ LAW FOR PERIODICAL RESEARCH OF RELIABILITY

Gompertz law is widely used as a model of the failure rate in the theory of reliability. It is often required to carry out computer experiments on model data when developing complex algorithms for data processing and comparing various techniques with each other. For periodic studies, it is required to simulate data on the time to failure of objects and data on the operating time of operable elements for a certain period of time, i.e. in general, the model data are two generated samples with distribution laws corresponding to the parameters of Gompertz law. Methods for generating such data that simulate cohort observations for the Gompertz law are well known. But there is no information in the literature on the law of distribution of the operation time of objects in a given stable population and on the methods of generating model samples in accordance with this law. This article fills this gap. From the Gompertz law, the distribution law of the operating time of workable elements is derived under the assumption of the stability of the set of elements. The inverse function of the integral distribution function of the operating time is obtained to generate random variables by the method of inverse functions. This function cannot be expressed in elementary functions, therefore, recommendations on the necessary approximate calculations are given in the paper.

Keywords: Gompertz model, failure rate, density function, random values generation.

FORMAL OUTPUT SYSTEM FOR A REDUNDANT SUBCIRCUIT IN GLOBALLY ASYNCHRONOUS LOCALLY SYNCHRONOUS CIRCUITS

The global trend of “green computing” has led to the emergence of new methods to improve reliability, which are focused on reducing energy consumption. One of these methods is redundancy at the transistor level. However, in order to improve reliability, the first step is to ensure the required level of reliability. However, developers often need to ensure high device performance. Consequently, optimization problems appear. In this paper, we propose a formal output system for the reserved subcircuit, which allows you to select the sections of the circuit that are optimal for reserving a certain method. The efficiency of the formal inference system is evaluated using a number of numerical experiments.

PARAMETRIC RELATIONSHIP BETWEEN MOBILE RADIO COMMUNICATION RELIABILITY AND COMMUNICATION NETWORK STABILITY

In the technique of electrical and radio communications, used parameters such as stability and survivability of the communication network. When assessing the quality of radio communications, a parameter of reliability of communication in time and in the radio coverage area has been introduced and used. This parameter is especially important for mobile communication systems, including cellular communications. Of course, the reliability of communication, determined by the requirements of noise immunity of transmission of radio signals, should be taken into account when assessing the stability of communication. Since the existing estimates of the stability of a communication network take into account only noise immunity, without taking into account the reliability of communication, it becomes necessary to determine the relationship of stability with reliability of communication. The article defines the methods for assessing the reliability of radio communications, survivability and stability of a communication network and their parametric relationship.

Keywords: network and radio communication system, noise immunity, fluctuations in the level of radio signals, reliability of communication, survivability and stability of the communication network.

CYCLIC PROPERTIES OF THE ORBITS OF PERMUTATIONS COGNITIVE MAPS OF PERMUTATION DECODER REAL­TIME SYSTEMS

Currently, there is an increased interest in the method of permutation decoding for systematic redundant codes due to the possibility of using cognitive methods for processing digital data in real­time systems. This allows you to give the decoding procedure of such codes a significant acceleration. The resulting gain in time is in demand in many applications, such as matching high­speed optical communication systems with the capabilities of processors for processing digital data in the format of advanced error correction, unmanned vehicle control systems, robotics, and other systems critical to time delays. The time gain is achieved by pre­calculating the generating matrix of equivalent code, the thin structure of which is set by the current permutation of characters in the code vector. The result of this calculation is stored in the decoder's cognitive map. This means that the time required to search for equivalent code associated with matrix calculations is replaced by the amount of memory on the cognitive map. Reducing this volume for real codes is a complex scientific and technical problem, the solution of which is proposed to organize on the properties of the orbits of cyclic permutations characteristic of both binary codes and codes with extended Galois fields. Special attention is paid to the combination of codes in the form of cascading coding schemes. For the first time, a description of such a scheme is given in relation to polar codes and non­binary Reed­Solomon codes (RS).

Keywords: soft symbol solution, permutation decoding, cognitive map decoder, concatenated code.

STUDY OF THE THROUGHPUT OF THE SYSTEM OF AUTOMATIC DEPENDENT SURVEILLANCE ­ BROADCASTING 1090 ES BASED ON MARKOV CHAINS

The paper is devoted to the problem of the throughput of the automatic dependent surveillance – broadcasting (ADS­B) system based on 1090 ES standard. This system is designed to transmit navigation information packets between aircraft and air traffic controller at 1 Mbit/s bitrate. The system uses random temporary access to the 1090 MHz carrier. If two aircraft begin to transmit simultaneously, the weaker signal is destroyed due to a collision. It is important to analyze the actual throughput of the 1090 ES system depending on the number of aircraft in the total airspace. This problem was raised in various works by various approaches, such as calculating losses by the probability theory method or even mathematical modeling of real airspace. In this paper we propose a method for calculating losses in the ADS­B 1090 ES system based on Markov chains, which allows one to take into account multiple message overlaps.

STATISTICAL PROPERTIES OF THE LOGARITHM OF THE AREA OF DELAUNAY TRIANGULATION ELEMENTS FOR UNIFORM DISTRIBUTION

Triangulation is used in many fields such as modeling of objects, geo­information systems, constructive geometry, and for spatial tasks of multiple nature. The triangulation is a Delaunay triangulation if there is no circle circumscribing around triangle element so that contains other points. Delaunay triangulation has useful properties, but there could be different methods of triangulation using other criteria for specific tasks. In this paper the triangulation is treated as an instrument which may be useful in the task of density estimation in two­dimensional case. It was previously shown by author for the one­dimensional distribution that logarithm of area under density function on the order statistics of the random variable may be used for density estimation. Of interest is opportunity to extend this result on the case of two[1]dimensional random variable. Triangulation may be treated as dissection of the density function definition area by minimal elements. The more value of density function in some subarea, the more density of experimental points, and though the less size of triangle elements. In this paper it is supposed that logarithm of the volume under density function on triangulation element could be used to estimate two­dimensional density function. Statistical properties of triangulation based on Poisson process are discussed in well known literature. Function of density for area of typical cell is derived for these conditions. Moments of the distribution are derived as well. But these results are not suitable for two­dimensional density estimation. In the condition of the problem in this paper, density of points is different on the subareas and is defined by density function only, so this condition does not fit to Poisson process. Because it is impossible to derive analytical expressions, characteristics of two triangulation kinds are investigated by numerical method for the case of uniform distribution on unit square. Empirical expressions are derived here for expectation and variance of logarithm of triangle areas of triangulation which is formed on less triangle perimeter criterion.

Keywords: Delaunay triangulation, probability density, logarithm of triangulation facets.

RESTORING THE REPEATED SEQUENCE OF PROBE SIGNAL IMPULSES WITH NONLINEAR COHERENT DISCRETIZATION

A method for reconstructing a periodic sequence of impulses with a known clock frequency in a virtual stroboscopic analyzer by rearranging, accumulating, and averaging discrete samples is considered. An array of data obtained using a gating analog­to­digital converter (ADC) is arranged in the desired order by calculating the position of each point in the selected signal recovery interval. When transmitting test and pilot signals in radio and telecommunication channels, it becomes necessary to restore the pulse sequence in noise. In many problems, the parameters of a test or probe signal are known: clock frequency, number of pulses and their shape – it is necessary to detect the signal and evaluate its shape or code sequence. It is shown that the method of permutation, accumulation and averaging of samples allows us to restore in the time domain not only periodic signals of arbitrary shape, but also repeating pulse sequences with a low signal to noise ratio. The basis of the complex is a personal computer (PC), in an empty slot of which an expansion card is included, containing modules of an analog adapter, digital­to­analog and analog­to­digital converters (DAC and ADC). At the output of the DAC, a signal is generated in the form of a test sequence supplied to the input of the radio channel in accordance with the test task. The results of testing and modeling are presented in the form of graphs of the initial samples and reconstructed signals.

Construction of effective system of radioelectronic means based on the analysis of the semumarkov model of electromagnetic compatibility support

Abstract

The article studies the processes of the functioning of the radio electronic system, consisting of many different radioelectronic means, which are subjected to unintentional and deliberate interference during operation. The subject of the study are models for ensuring the electromagnetic compatibility of a set of radioelectronic facilities. The aim of the work is to select the optimal work plan for a variety of different radioelectronic systems and facilities in order to increase the efficiency of their joint functioning by adjusting the parameters of the emissions. For this purpose, the application of a probabilistic approach to the analysis of the dynamics of states of the model of the functioning of radioelectronic facilities based on the theory of semiMarkov processes is proposed. As a result of this approach, models were obtained for calculating and analyzing the efficiency of the functioning of radioelectronic facilities, differing in systemic account of all the factors affecting their joint work and the reliability of formalization of the description of the process. On the basis of the proposed models, it is possible to carry out optimal planning of the frequency resource in order to reduce the level of interference for radioelectronic facilities, and this means to form an effective radio electronic system equipped with various types of radioelectronic means. The proposed models allow not only to analyze the effectiveness of the functioning of the system of radioelectronic facilities, but also to solve inverse problems to improve their security to the required level.

Fault tolerant D latch

Currently, the design of electronic equipment on programmable logic integrated circuits (FPGA) is actively developing. Modern FPGAs contain billions of transistors and tens of millions of logic elements. FPGA (fieldprogrammable gate array) uses configurable logic elements CLE containing the socalled LUT (Look Up Table) and a synchronous flipflop of D type. But logic takes up a smaller part of the FPGA than memory. The configuration memory is an SR flipflop of SRAM static RAM cells. Recently, the development of FPGA for critical applications, for example, for radiationhardened equipment, is being used, for which redundancy is used. Previously, faulttolerant LUTs and SRAM cells were proposed. The article investigates the peculiarities of the D Latch and suggests fault tolerant solutions.

Interference-coding in avionics

Abstract

Voice communication systems are used when an air traffic controller/pilot needs to pass command signals to confirm or pay attention the received message. The majority ofaccidents occur due to actions by operational personnel. So, activities of the air traffic controllers and pilots is directly related to the flight safety and efficiency ofairlift.

Aeronautical radio communication is the most important communication type, because it is the only possibility contact between controllers and pilots. Aeronautical radio communication must perform the main functions, such as: regular (constant) voice communication in all phases of flight and determined level ofquality. Air Traffic Management (ATM) operates in a large amount ofdata processing and transmission. The radio frequency spectrum is important natural resource, which has limited capacity and the need for this is increasing. Using of classical analog techniques for voice communications accelerates the time of spectrum saturation. Using of modern digital solutions for speech coding - vocoder - may reduce the necessary  transmission bandwidth and to improve the communication quality.

THE CELL OF FAULT­TOLERANT UNCOMMITTED LOGIC ARRAY WITH RESERVATION AT TRANSISTOR­LEVEL

Abstract

The development of VLSI designing with use of an uncommitted logic array (ULA) is very important for domestic electronic industry. The standard cell use four CMOS transistors. The redundant structures is need for designing of high reliable, fault­tolerant, radiation­tolerant electronic components. Triplication is often uses for this task, the three channels of discrete circuit is connected with special major gate which implement choice function (for example 2­of­3, ≥2). The n­of­m redundancy is commonly used in critical computing systems with passive fault­tolerance. It is known that such redundant structures provides advantages for reliability not for all time range. The authors proposed another technique using redundant transistor structures for fault­tolerant computing systems as an alternative to n­of­m redundancy. In the beginning this structures was considered as functionally complete tolerant gate (FCT) that save functions or functional completeness in case of failure. Further the technique for redundant transistor networks was developed. However, the research into the synthesis of redundant cells for ULA was not done yet. In this paper, the development of redundant cell for ULA is presented and the reliability of these cells are analyzed.

DIRECT NARROW-BAND GAUSSIAN FREQUENCY SHIFT KEYING SIGNALS DIGITAL SYNTHESIS

Abstract

Compact and low processing gain narrow-band Gaussian frequency shift keying (GFSK) signal forming method is being proposed based on direct digital synthesis principles. This method provides high precision frequency modulated signals generation with high spurious-free dynamic range. GFSK modulator structure, block diagram and design procedure according to the method proposed are presented. The modulation curve matrix is stored in the form of consequential equivalent (due to quantization) amplitude samples table; its compression mechanism and algorithm are proposed, based on their quantitative factor. For the eight bit per sample signal the modulation curve matrix compression table and the memory access algorithm are designed. The main simulation results carried out for the method proposed are presented – power spectrum density and nonlinear components level. For example, the method provides 6 dB lower nonlinear components level as compared with quantization noise and 10 dB lower as compared with traditional DDS generator on eight bit per sample signal. For sixteen bit per sample signal the nonlinear components level provided is 98 dB lower as compared with the carrier level.

I.R.Dubov Nonparametric estimation of a logarifmafunktion of intensity refusals on experimental data

Annotation

Nonparametric approach to failure rate function estimation gives us possibility to assess reliability of some elements under uncertainty conditions. Nonparametric approximation of failure rate function is discussed in the paper. It is based on data of period observation for some population. The idea of the proposed approach is based on the fact that the logarithm of the failure rate function is defined by the difference of two probability density functions. The first one is probability density function for failures of elements observed during the observation period. The second one is probability density function for the elements age. As has been shown in previous papers by the author, direct observations of the logarithm of the probability density could be constructed on the base of order statistics. These direct observations are independent of the source distribution of the random variable. Direct observations of logarithm of failure rate function are proposed in this paper. Such observations are based on the direct observations of density functions and so ones are independent of failure rate function itself. Variance of the estimates is determinate and Mallows criterion may be used for nonparametric regression. So the problem of failure rate function estimation is reduced to nonparametric regression. Each approximation function is to be constructed by least squares method. The optimal function is to be chosen according approximation criterion. Set of polynomial functions or kernel estimators could be used here. Potentiating result function we obtain desired approximation of failure rate function. The paper presents a demonstration of approximation procedure on model data.

Key words: failure rate, nonparametric estimation, probability density, approximation criterion
