New Trends in Telemetry

Abstract

Telemetry systems in widest user are the FM-FM frequency division, and the PAM, PDM, and PCM time-division systems. A new hybrid system, PACM, could be used to combine the advantages of both PAM and PCM. In the future there will be marked improvement in speed, accuracy, and reliability of telemetry systems, along with reduction in size, weight, and cost.
