The main disadvantage of this method is associated with the sensitivity of this method to harmonics, noise and flicker of the measured signal. The existing methods of reducing the measurement error results to an increase of the measurement time, which is a significant disadvantage for a number of practical tasks. This paper discusses a method of reducing the frequency measurement error when applying the zero-crossing technique. The proposed method is based on the determination of the moments of signal transition through the level which corresponds to signal maximum derivative. To clarify the moments of signal transition through a given level, a piecewise-linear approximation of the signal in the vicinity of its transition through a given level was applied. To determine the value of the derivative, a seventh-order digital differentiator is proposed. Analytical expressions for the frequency measurement error estimation for the proposed measurement method are obtained. The effectiveness of the proposed method of reducing the measurement error in comparison with the “traditional” zero-crossing technique has been evaluated. By using the Simulink software package, a model of simulation modeling of a frequency measurement transducer that implements the proposed measurement method has been proposed. The reliability of the obtained analytical expressions is confirmed by the coincidence of the results of simulation modeling and analytical expressions at check points.","PeriodicalId":374410,"journal":{"name":"2020 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133584058","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 important to ensure compatibility between them. The key component for that is the code converter, which can, without proper frequency specifications, be the “bottleneck” of the whole system. High data transmission density implies increasing of digital signal frequency. Thus, circuits for high frequency applications face high requirements. The siliconbased technologies often concede in terms of frequency capabilities. Using GaAs-based pHEMTs is one of the possible ways to overcome this. It might be useful for logic circuits in which data transfer speed and early decisions are crucial.

One of the most common and effective methods for diagnosing CVD is to record an electrocardiogram using Holter monitoring. In order to significantly reduce the time required to decrypt the recording of ECS, cardiologists need special programs for automated analysis of the electrocardiogram. This is especially important for the long-term monitoring task. The program for the automated analysis of pacemakers should perform the clustering of cardiac complexes, thus dividing the electrocardiogram into groups of individual cardiac complexes. Only reference cardiocomplexes obtained by statistical averaging from each such group are subjected to further analysis. When registering an electrocardiogram, interference of various physical origins arises, artifacts that significantly complicate the analysis of ECS, therefore, automated analysis programs must also carry out preliminary processing of the electrocardiogram.","PeriodicalId":374410,"journal":{"name":"2020 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"47 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116396814","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}
