Abstract

A quasi-moving average circuit constituted without use of a conventional shift register, and constituted by a subtracter which subtracts output data at the preceding sampling time from input data at the sampling time at present and outputs subtraction data; an accumulator unit which adds the subtraction data from the aforesaid subtracter and the accumulation data obtained by accumulation by an amount of a predetermined number of times of samplings up to the preceding sampling; and a division means which divides the accumulation data from the aforesaid accumulator unit by N (1/N), thereby outputting an average value of the N sampled values as the output data at the sampling time at present.
