By using the Moodle platform, the developed course provides to the students, regardless of location and time, access to all necessary learning materials, including homework, self-assessment tests, electronic circuits and communication tools. Moreover, in the learning process, the students have opportunity to access assessments and feedback messages, which increases their engagement and motivation. In the Moodle environment the teachers have a constant global view of student progress and have a variety of tools, such as video conferencing for discussions, sending feedback messages for homework, obtaining statistics and performing additional verifications of the separate academic groups. The analysis of the student evaluation results showed that the use of the distance learning course can increase the effectiveness of the training and create skills, such as using computer-aided design systems, information technologies and teamwork.","PeriodicalId":178356,"journal":{"name":"2020 XXIX International Scientific Conference Electronics (ET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126341402","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 filter is called “reduced” because it processes samples that are distanced in a quarter of power-line period. During the extraction of the interference, an assessment of power-line frequency is performed and an appropriate adaptation of the coefficients of the reduced filter is performed. The reduced band-pass filter is suitable for mains interference rejection, as well as for its frequency measuring.","PeriodicalId":178356,"journal":{"name":"2020 XXIX International Scientific Conference Electronics (ET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129450149","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}
