Description: Since historically much of the early development of analog electronics took place in the communication field present, day students understanding of electronics can be enhanced by working with FM communication circuits. Students majoring in the electrical and computer engineering concentrations at our university are required during their junior year to take a three hour lecture course and a two-credit-hour lab course in analog electronics. By the end of the courses, students learn the theory and application of such components as diodes, Zener diodes, NPN and PNP transistors, MOSFETs, SCRs Diacs, Triacs, and optoelectronic devices.
New experiments have been added to the electronics lab to enhance understanding of basic analog components. This project investigated the effects on the students learning of analog electronics by having them develop an FM transmitter and an FM receiver circuit much earlier than they are prepared to handle them. Electronic communication circuits are studied in detail a semester later in the second electronic course and RF theory is introduced a year later in the communication courses. The objective for the student was to discover how the electronic components studied in class can be placed together in an FM transmitter to work as: a signal amplifier, local oscillator, FM modulator, frequency multiplier, and power amplifier at the final output stage. In an FM receiver they see the components working as: an RF amplifier, local oscillator, FM mixer, IF amplifier, FM detector, output audio amplifier and automatic frequency control circuit. Students also learned to appreciate the modular nature of complex designs. At the end of the semester, a survey was given to determine the results on student learning concerning the concepts and applications of electronics. The results of this project may prompt the implementation of other projects that may include multidisciplinary collaboration, integration of projects between classes, projects across concentrations, and integration of a single project from the freshman to the senior year.
