RCA 76,533 Abstract of the Disclosure A frequency selective chrominance signal translating circuit for use in a color television receiver employing a comb filter is disclosed. The comb filter responds to switching signals for providing separate outputs from which the luminance and chrominance television signal components are derived. The translating circuit includes first and second cascaded, bandpass filters tuned to frequencies above the chrominance subcarrier frequency. The first filter receives comb filter output signals including desired chrominance signals and undesired components at the frequency of the comb filter switching signal. The circuit prevents unwanted high frequency components, particularly those associated with the comb filter switching signals, from reaching the color demodulators of the receiver, and translates signals from the chrominance output of the comb filter for supplying chrominance signals to color demodulators with a substantially symmetrical amplitude response and linear phase response as required for proper color demodulation.
