CERTAIN CIRCUITS FOR CONVERSION OF VOLTAGE INTO BINARY CODE (NEKOTORYE SKHEMY PREOBRAZOVANIYA NAPRYAZHENIYA V DVOICHNYI KOD),
Abstract
Two voltage-to-digital conversion circuits, based on semiconductor elements, have been developed with special emphasis on simplicity and reliability. Since the circuits are designed for use in telemetry systems, no special requirements for high speed were included. The first of the circuits employs a pulse counting conversion method with feedback. It consists of a pulse generator, binary counter, a zero-indicator, a decoder, and a gate. Two methods can be used to transmit the data, i.e., either in binary code or in pulses, the number of which is proportional to the measured voltage. In the second proposed circuit, the conversion is accomplished by means of binary 'weighing.' The coding operation in this circuit is performed in two basic steps: digital comparison of the converted voltage with a standard one, and subsequent code readout.
