Basic Signals and Modulation

Thursday, October 29th

Steve Horan, NASA Langley Research Center

Course Description
This course is directed towards beginning technical personnel or telemetry personnel with limited experience in communications and modulation systems. The course will cover basic concepts necessary to understanding the data communications process within the telemetry system.  This will include signal descriptions, the Pulse Code Modulation (PCM) process, concepts of analog and digital modulation and demodulation, and signal bandwidth representations.  Emphasis will be on graphical representations with minimal mathematical requirements.
