ABSTRACT:
In accordance with the present invention, there is provided an economical and compact frequency sampling filter comprising a comb filter and resonators, in which the difference between the output of a frequency sampling filter of the bandpass type or the low-pass type, or the bandstop type or the high-pass type and the output of a circuit having the same gain as that at each sampling point in the pass band of said filter and having a similarly varying phase to that in the pass band is obtained.
