Development and Analysis of Algorithmically-Controlled Adaptive Analog Filters as Components in Information and Measurement Systems

Abstract

This paper describes a measurement-circuit design approach based on switched-capacitor filters, and an analog vibroacoustic signal-matching-and-conversion device. We also develop an adaptive control algorithm for measurement-circuit parameters, and find that analog matching devices can be used advantageously for and monitoring and diagnostics of process status in industrial equipment.
