A digital radiosonde system

Abstract

A study of the present methods and equipments used in obtaining upper air meteorological data indicated a need for a new system capable of interfacing with digital equipment. This work deals with establishing the parameters, methods of implementation, circuit design, construction, and testing of such a system. Sampling, pulse width modulation, time multiplexing, pulse width to digital conversion, and interfacing with the digital computer are discussed. The proposed integrated circuit radiosonde system was constructed and tested with results indicating an improvement over the existing methods.
