Abstract

PURPOSE:The noise is detected from the point where the signal in the feedback circuit net becomes 0, and the feedback quantity against the noise is increased, whereby it possible to sharply control the noise without varying the profit of negative feedback amplifier, by means of the simplified and less expensive circuit constitution.
