Description
This paper describes a FM demodulation circuit simulation and implementation project for use in an undergraduate course in communications for electrical engineering students. The purpose is to provide a hands-on project to enhance undergraduate students understanding of the demodulation of FM signals. The project provides an alternative view point to the complicated mathematical descriptions using transform theory that are commonly provided in modern undergraduate communications texts. This low cost exercise provides an actual circuit implementation using both a hardware and software realization to allow for signal tracing. It is an ideal supplement to a three hour lecture course which does not have a companion laboratory. The circuit implementation includes a narrow band frequency modulated waveform which is demodulated using a simple slope detector circuit. The paper outlines the learning objectives, and how they align with the ABET program outcomes. It also provides an introduction to the FM modulation theory along with an overview of the necessary circuits and concepts.
