Distorted input signal processing circuit has filter whose filter coefficients are influenced by comparison signal produced by equalized signal from filter and output signal of threshold decider

摘要

A distorted input signal (S1) is supplied to a filter (10) which produces an equalized signal (S2) which is supplied to a threshold decider (31). The equalized signal and the output signal (S3) of the threshold decider produce a comparison signal (D) that influences the filter coefficients (FK1) of the filter.
