Abstract
A CCD comb filter includes long and short CCD delay lines connected to receive a common input signal and is arranged to combine output signals of the long and short CCD delay lines. In order to realize a CCD comb filter very close to an optimum comb filter the product of the number of stages of the long CCD delay line and the transfer inefficiency of each stage thereof is set substantially equal to the product of the number of stages of the short CCD delay line and the transfer inefficiency of each stage thereof. In order that the transfer inefficiency of the short CCD delay line may be made greater to satisfy the above-mentioned requirement, transfer electrodes of the short CCD delay line are designed such that their length as viewed in charge transfer direction is made larger than the length of transfer electrodes of the long CCD delay line.
