ABSTRACT OF THE DISCLOSURE Disclosed is a programmable frequency converting filter having a plurality of a selectable operating modes, and having frequency passbands of a unique width for each of the operating modes. The programmable frequency converting filter is comprised of a charge transfer device transversal filter, a non-sampling filter, and a frequency band selector. The transversal filter has an output lead coupled to an input of the non-sampling filter, and has clock leads coupled to the output of the frequency band selector. The frequency band selector has control leads for receiving logic signals which together select operating modes from the plurality of modes. The frequency band selector generates, on the clock leads, clocking signals having a unique frequency for each mode of the plurality.
