AC-DC comparators for audio-frequency current and voltage measurements of high accuracy

Abstract

This paper surveys recent developments in high-accuracy ac-dc comparators, the basic standards for ac current and voltage measurements at audio and higher frequencies. These instruments compare the unknown ac quantity with a dc reference. The ac-dc transfer characteristics of thermal converters, the most widely used comparators, can be evaluated to about 10… (More)
