ABSTRACT:
A band-pass filter comprises a delay circuit comprising a plurality of unit delay elements connected in cascade arrangement and receiving as input a signal including a frequency modulated signal and a coefficient summing circuit for carrying out coefficient summing of the outputs of specific delay units of the delay circuit and producing as output the frequency moudlated signal which has been band-pass filtered. This band-pass filter has a transmission characteristic representable by
