Abstract

PURPOSE:To prevent oscillating phenomenon due to mixing of noise in rejecting ghost through the use of a cyclic filter consisting of a weight circuit and the like, by providing specific addition, comparison and subtraction means, respectively. CONSTITUTION:A cyclic filter 2 consisting of a plurality of delay circuits 8 and weight circuits 10 and the like, is used, and the amount of waveform distortion is detected from a specified signal part in an output signal of the cyclic filter 2, and the weight of the circuits 10 is adjusted so that the amount of waveform distortion can be decreased. The waveform distortion rejector is provided with an addition means 14 obtaining the said weight value or its equivalent value of total amount of the absolute values, a comparison means 15 comparing the total mounts of the absolute values with a constant value alpha, and a subtracting means 17 decreasing the said weight value by a prescribed value delta when the total amount of the absolute values exceeds the value alpha.
