The construction of an analog vocoder as a hands-on introductory course in electrical engineering

Abstract

This paper describes the Tallerine-Vocoder, a hands-on course for Electrical Engineering (EE) freshman students. This course aims to motivate students and stimulate their creativity meanwhile the objects, topics, methodologies and actors of the EE program are also introduced. Throughout the course, students build and test all the necessary modules to assembly an analog Vocoder. The Vocoder modules are briefly explained and the course methodology exposed. Finally, the main goals of the course are objectively evaluated by a student survey and discussed in the results. Keywords : active learning methodologies, hands-on, electronics and music, vocoder
