PURPOSE:To cancel a waveform continuing longer at the outside of a tap of a transversal type filter by combining cyclic filters. CONSTITUTION:A cuclic filter 5 is connected in cascade to noncyclic filters 1-4, and an output 106 via a tap weight K at the outside of the filter 5 is added with tap weight outputs 11-14 of the noncyclic filters 1-4 by an adder 31. On the other hand, the coefficient in the feedback path of the cyclic filter 5 is controlled by the output of the cyclic circuit 5, the tap weighting is corrected sequentially together with the input of a new data and converged.
