Abstract

PURPOSE:To facilitate formation by eliminating the phase difference of an output signal while eliminating the shunt of a weighting circuit and feedback circuit with the same bits, by leading a feedback signal and positive-phase addition signal out of respective stages of cascaded delay elements. CONSTITUTION:An input signal is input to one-side terminals of cascaded delay circuits 4, 5, 11 and 12 equal in delay time according to transfer function G(Z). Feom output terminals of delay circuits 4 and 5, signals are fed back by way of weighting circuits 8 and 9 with weighting coefficients b0 and b1, thereby performing addition. At output terminals of delay circuits 11 and 12, signals appear and are added together in positive phase by way of weighting circuits of weighting coefficients a0 and a1. COnsequently, band-passing characteristics shown by formula (4) can be realized.
