Abstract

PURPOSE:To make steep the characteristics, by enabling to increase the number of orders with comparatively small circuit scale, in the non-circulation type filter processing sampled digital signal. CONSTITUTION:The filter has the multiplication block 15 having N sets of output terminals which input digital input signal sampled by taking the sampling period as T and output the output of different multiplications, and a plurality of distribution blocks 16 to 18 which input M sets of outputs of the block 15 and have N sets of output terminals connecting the i th (i=O to N) output terminal to either one of the M sets of input terminals. Further, it provides the addition block 20 which adds the output at the output terminal corresponding to the blocks 16 to 18, multipliers 19,21 which are connected to the input of the blocks 16 to 18 and performs digit shift, further provides adder which supplies the output corresponding to N-1 sets of outputs among the outputs of the block 20, and delay units of N-1 sets having delay time T in the block 15, to constitute the circulation type digital filter through cascade connection with delay units and adders.
