Filed: 1979-08-13
Abstract: PURPOSE:To improve an SN ratio by finding a subsegment that includes the largest sampled value of sampled values in one block of an input signal and by multiplying sampled values in the block by a coefficient that corresponds to it. CONSTITUTION:A PCM code from input terminal 101 is led to maximum-segment- number extracting circuit 107 as well as delay circuit 102 that remembers an input signal for one block of N samples.
