Consideration of RF Parameters for PCM Telemetry Systems

Considerable differences of opinion have existed concerning the requirements for transmission of PCM information. Quite often, PCM has been accepted as a system inherently requiring wide RF bandwidths and correspondingly poor noise performance. This paper considers selections of RF parameters for PCM telemetry systems. It points out that if these parameters are correctly chosen, the bandwidths and sensitivity of a PCM system may be made comparable with those of other existing telemetry systems.
