Telemetry in The Classroom: An Excellent Teaching Tool

Abstract

University communications courses typically use broadcast AM and FM as practical examples of fundamental concepts. We propose telemetering based applications which illustrate these fundamental concepts in a more complete manner. This paper presents two simple laboratory experiments which construct simple one-way telemetry links using standard components available in most RF laboratories. The first system is an RS-232 data link and the second system is an analog video system. The performance limitations of these systems illustrate the complexity-performance trade-offs inherent in all communications systems.
