An input of a charge coupled device (CCD) delay element (6) is an additional signal of a reproduced luminance signal and a reproduced chrominance signal, while an output of the CCD delay element is separated by an LPF (7) and a BPF (9) into a delayed luminance signal and a delayed chrominance signal, thereby constituting a comb filter by using the input signal before an addition and delayed/reproduced signals. Accordingly, it is unnecessary to provide a filter for limiting a band width, which is inserted into a main signal path. Furthermore, since it is possible to constitute a comb filter which does not narrow a signal band width of the reproduced luminance signal and the reproduced chrominance signal, there can be provided a comb filter for removing a cross-talk and noises and which does not narrow a signal band width of the luminance signal and the chrominance signal. <IMAGE> |
