Abstract

PURPOSE:To prevent the oscillating phenomenon due to noise, in rejecting waveform distortion such as ghost through the use of a cyclic filter, by providing a specific addition means, the 1st and end comparison means and a subtraction means. CONSTITUTION:An addition means 14 obtaining the total amount of the absolute values of weight value or its equivalent from a plurality of weight circuits in a cyclic filter, and the 1st comparison means 15 comparing the total amount of the absolute values with a prescribed value alpha smaller than that at the presence of waveform distortion, are provided. Further, the 2nd comparison means 17 comparing the absolute value of each said weight value with a prescribed value beta when the total amount of the said absolute values exceeds the value alpha, a subtracting means 19 reducing the absolute values of weight values by a prescribed value delta and giving correction when the absolute values of the weight values are smaller than the values beta, are provided. Further, the weight values corrected by the subtracting means 19 are outputted as the weight values of the said weighting circuits.
