HIGH RESOLUTION PULSE RATE MODULATED DIGITAL-TO-ANALOG CONVERTER SYSTEM

摘要

This disclosure relates to a pulse rate modulated digital-to-analog converter system which translates the digital information into a train of identical pulses, with the pulse rate proportional to the digital data. The pulse train produced by the encoder drives an analog switch, which in cooperation with a filtering analog circuit, converts the pulse train to an analogous DC voltage.
