Abstract

PURPOSE:To constitute a desired signal rationally and inexpensively, by using weighting circuits and adding circuits of plural sequences for one delay circuit with tap in case that a waveform equalizer and a correlator are realized simultaneously for the same input. CONSTITUTION:A transversal filter 28 consists of a delay element 16 consisting of basic delay elements D1-Dn, tap outputs 17-21, weighting circuits 22-26 connected to respective tap outputs, and an adder 27 which adds and combines outputs of respective weighting circuits. A transversal filter 35 of another system consists of weighting circuits 29-33 to which tap outputs 17-21 of the delay element 16 are inputted similarly to weighting circuits 22-26 and an adder 34 which adds and combines outputs of weighting circuits 29-33.
