Abstract

PURPOSE: To remove spike noises occuring in sound signals, by obtaining a noise section signal through the comparision between outputs of two integrating circuits which are different in time constant, by making the signal in the section coincide with a demodulated sound signal in timing and by holding the section sound signal in the noise section at the level immediately before the noise section occurs.
