INCREASING IMMUNITY TO NOISE AND INDUSTRIAL INTERFERENCE OF HIGHLY SENSITIVE MEASURING CHANNELS OF THE SENSOR SYSTEMS

Abstract

The article discusses the new construction principles of the highly sensitive and high-speed electronic channels for sensor measuring systems with parallel-sequential conversion of the dynamic informative signals of direct or alternating current in wide ranges of its amplitude and frequency. The possibilities of improving suppression of noise and the interferences on industrial power frequency with several methods of processing the obtained data shown analytically and experimentally. A prototype of a unified basic module of the measuring channel described, intended for the implementation of information-measuring systems for various purposes; its main characteristics are given.
