PURPOSE:To simplify the hardware constitution by providing two integration devices whose phase is deviated by muT and integrating a changeover switch output for a period of 2muT and a sampler sampling the result of integration alternately at an interval of muT. CONSTITUTION:A data sampled at a period T and inputted to an input terminal 1 is integrated by an integration device 10 and the polarity of the result of integration is changed by a polarity inverting device 20. The result of integration and polarity inversion is inputted alternately to integration devices 5, 6 of the next stage by a changeover switch 30 at an interval of muT and integrated for a period of 2muT. Through the series of operation, an impulse response string and an output of an integration device 10 are subject to convolution operation for a length of 2mu. The integration devices 5, 6 apply integration so that the convolution operation has a phase difference of muT and the result is sampled by a sampler 7 at an interval of muT.
