Abstract : The report describes the research and development study of a pulse duration modulation multiplexer for use in personal telemetry systems. The objective of the program was to develop a low power, accurate pulse duration modulation multiplexer which has the potential of small physical size and low weight. The technical approach includes the design of low power logic, the use of the most advanced multiplexer switch, and the development of a unique amplification and comparison technique. All the system general requirements and specific requirements are satisfied by the design. The system performance is demonstrated by a laboratory breadboard model. Results of the tests performed on the model verify the feasibility of the engineering design. (Author)
