The results of the research in this field are used in many areas of science and technology to solve a wide range of problems. Many of these problems require the use of approximation theory methods for signal processing. The use of approximation methods for signal theory is one of the most necessary nuances related to their digital processing. Classical approximation theory methods used to construct an approximation of a continuous signal, as a rule, are based on the use of a set of certain values of the function representing the studied signal, at predetermined values of the independent variable. When working with signals, we use interpolation to solve such problems. In such cases, classical interpolation methods such as Lagrange interpolation polynomials or other interpolation methods, such as those based on Fourier series are used. However, most of the interpolation methods of the type indicated above do not always give optimal results in terms of approximation quality or require a lot of calculations compared to other approximation methods. In this work, a new, more effective method of interpolation has been proposed. This method makes it possible to restore a continuous signal qualitatively using its discrete representation. We found that the introduced trigonometric interpolation polynomial allows obtaining a higher quality of signal restoration in comparison with the often considered Lagrange interpolation polynomials. Also in the paper, a comparative analysis of the proposed introduced trigonometric interpolation polynomial with the widely used Lagrange interpolation polynomial has been carried out. We have shown that the trigonometric interpolation polynomial introduced in the work gives the better approximation and requires significantly fewer calculations.","PeriodicalId":264053,"journal":{"name":"2022 IEEE 4th International Conference on Advanced Trends in Information Theory (ATIT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126307847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is outlined that studying this procedure using analytical methods is not sufficiently graphic and straightforward. To improve performing assessment of antenna-feeder matching characteristics, the authors propose using a computer simulation model of a transmission line loaded with specified impedance that can be both complex and real. The computer simulation model is based on trapezoidal rule, which is characterized by robustness as to error accumulation. The computer simulation model is used to study antenna-feeder matching scenarios for the feeder with 50-ohm real impedance and the antenna impedance ranging from 40 to 70 ohm. As the signal, the radio pulse of a certain duration is used. Computer simulation results have illustrated the characteristics of antenna-feeder mismatch with good clarity and precision. Thus, the trials showed not only the level of the signal reflected from the mismatched antenna, but also its form and the process of reflection in dynamics. The proposed method based on the computer simulation model can be used for improving antenna-feeder matching assessment in the fields of telecommunications and radars at microwave frequencies of operation.","PeriodicalId":264053,"journal":{"name":"2022 IEEE 4th International Conference on Advanced Trends in Information Theory (ATIT)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115605635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In foreign literature, scientists often consider the problems related to the study of a signal in the amplitude and frequency plane. In such situations, Fourier series are suggested to use. However, in some works, including foreign ones, this problem is solved using not the series themselves, but their partial sums or other methods based on them. This work shows that partial Fourier sums are not the optimal method for studying signals, including when they are restored to the continuous form. As an alternative to partial Fourier sums, we have proposed to use Fourier series summation methods in this paper. As an example of this use, the Abel-Poisson method has been considered. When comparing the efficiency of the Fourier and Abel-Poisson partial sum methods as signal representation methods, we have shown that the Abel-Poisson method allows getting better signal restoration. We have also revealed that the Abel-Poisson method is saturated and, accordingly, more predictable when being used. This allows building better signal processing algorithms than those based on the partial Fourier sums.","PeriodicalId":264053,"journal":{"name":"2022 IEEE 4th International Conference on Advanced Trends in Information Theory (ATIT)","volume":"236 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124524375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work is devoted to solving the problem of designing and researching the information system for optimal control of the vacuum membrane distillation process. The driving force is maintained by applying a vacuum on the permeate side in vacuum membrane distillation. The applied rarefaction is less than the equilibrium vapor pressure. A model of the vacuum membrane distillation process was created, which takes into account the temperature distribution of bioethanol in the solution and permeate along the length of the channels of the membrane module and the distribution of the concentration of bioethanol in the solution in the channel. In order to reduce unwanted energy costs, which are associated with changes in the characteristics of the microstructure and thickness of the membrane during operation, entropy was chosen as an optimality criterion. The maximum principle was used to calculate optimal software control. Variants of the criterion of optimality are considered. The calculation of the optimal software control using the gradient procedure has been implemented.","PeriodicalId":264053,"journal":{"name":"2022 IEEE 4th International Conference on Advanced Trends in Information Theory (ATIT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131857064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
