Noise eliminating circuit

摘要

A noise eliminating circuit including a subsignal modulator circuit, a matrix circuit, and sample-and-hold circuits, for reducing signal distortion as well as preventing the in-circuit generation of noise. The sample-and-hold circuits are disposed in the signal paths of a main signal and the demodulated subsignal and are operated by a signal synchronous with a noise component. The holding times of the two sample-and-hold circuits may be made different from one another.
