Abstract:
PCM technology offers significant advantages in the application of telemetry to medical and physiological studies. The requirements for less complicated handling, standardized system layout, improvement of weight, size and power supply by commercial battery modules, as well as different wireless data links are met better by a PCM encoder which was specially developed for physiological applications. The advantages of PCM are illustrated in this paper by relating the experimental requirements to technical specifications for the elements of a telemetry link. A newly designed 8-channel PCM-telemetry system satisfying these requirements is described.
