title: Pulse width to analog converter for a portable radio telemetry receiver.
abstract: A pulse width tracking system is described which converts a pulse width modulated telemetry signal into an analog signal. The converter, which is based on an integrated circuit chip design, contains a feedback feature that makes it ideal for high stability servo applications. The converter was designed as an integral part of a long-range radiotelemetry system used in occupational health field research.
