ABSTRACT:
System comprising an integrating digital signal processing device to which input signal samples x(nT) are supplied with a period T and which supplies output signal samples z(mrT) with a period rT. To this end in this integrating signal processing device consecutive groups having a period rT and consisting of r successive consecutive signal samples are processed beforehand in a non-recursive digital filter for generating auxiliary signal samples y(mrT) which occur with a period rT, the last mentioned samples being integrated in an integrating network for generating the output signal samples z(mrT).
