Abstract
A color television receiver includes a comb filter responsive to detected video signals for providing a wideband combed chrominance signal, which is coupled to chrominance processing circuits via a composite filter including plural mutually interactive resonant sections. An input resonant section of the filter serves to remove very high frequency interference signals including comb filter switching components from the chrominance signal path, and also coacts with the other filter sections to provide an amplitude characteristic having a sense to compensate for an oppositely directed amplitude characteristic associated with the detected video signals, over the passband of the wideband chrominance signals.
