Implementation of the educational software analog modulation systems

Abstract

The use of new technological tools for the development of experimental practices within the classrooms and laboratories has contributed to the development of new skills by students in both the academic and professional fields. For this reason, this research work aims to implement a software Analogic Modulation System using the App Designer tool of MATLAB. For the development of this research, the bibliographic, experimental, and research method was used to cover the entire required research field. In order to apply the research method, surveys were applied by selecting the 36 students of the Analog and Digital Communications subject in the seventh semester of the 2018-2019 academic period of the Teleinformatic Engineering degree at the University of Guayaquil. The results of the surveys indicate that the system is useful, intuitive, reliable, and efficient but not as user-friendly because 81% of the respondents believe that it is. It was also determined that the students who are taking an experimental subject want to manipulate equipment that is available in the laboratory because they have the perception that they can learn more even if it takes longer to develop these experiments. In relation to the tests carried out, it is deduced that they were successful because the signal message can be recovered without error even though it was transmitted in different media and also using different analog modulations. The only discrepancy that existed was the time of transmission of the data.
