Abstract

PURPOSE: To improve the compression property at the rise part of an input signal as well as the expansion property by controlling the amplification performance of an amplifier by means of the composite signal of the DC voltage proportional to the scale of the input aural signal and the signal obtained by differentiating the peak detection value.
