Desenvolvimento de um aplicativo web educacional para auxiliar no ensino remoto de processamento digital de sinais

Abstract

The COVID-19 pandemic contributed to the cancellation of face-to-face classes at universities around the world. As a result, educational institutions had to radically remodel their teaching-learning techniques, taking into account the use of remote teaching tools and platforms. One of the main problems faced by public institutions is the digital inclusion of students in situations of economic vulnerability. These students hardly have a computer with software licensed at home to apply concepts of digital signal processing without depending on the laboratory of the educational institution. Based on these premises, the present work presents the development of an educational web application to assist in the remote teaching of digital signal processing, using a smartphone, computer or tablet. The application works online, the student can access remotely through a link. From the results presented, it is possible to observe that the Web application performed well both in remote access and in the application of signal processing techniques.
