SELF-TUNING SYNCHRONOUS FILTER,

Abstract

A self-tuning synchronous filter for selecting signals with respect to shape is introduced. It consists of a multiplier, an adder stage, delay lines, phase shifters, and limiting amplifiers. To separate a weak quasiharmonic signal from strong fluctuating background noise and to simplify the multiplier circuit, the latter is designed in the form of two bridge-balanced transistor modulators.
