Miniature Digital Telemetry System Employing Cyclic Time Multiplexing Designed for Potentiometric Transducers.

摘要

The paper describes the design and testing of a miniature multi-channel digital telemetry system designed specifically for use in remote controlled model aircraft experiments coordinated by the Aeronautical Engineering Department at the Naval Postgraduate School. The avionics package comprised of data encoder/multiplexer circuitry and a transmitter is lightweight,inexpensive,small in physical size,has low current drain and is capable of transmitting up to nine channels of data. The system was designed specifically for transducers with potentiometric outputs although transducers having voltage or current outputs can be interfaced with the system. The thesis emphasizes the engineering design requirements and working design models to achieve efficient system performance. (Author)
