A comb filter circuit for separating luminance and chrominance signal components from a composite color television signal transmitted with the luminance and chrominance signal components in a frequency interleaved relation, comprises a delay means for delaying the composite color television signal by one horizontal scanning period and a bridge circuit connected to the delay means and consisting of four sections of substantially equal impedance. To the bridge circuit the delayed and non-delayed composite color television signals are suppled and therein the addition and the subtraction of both signals are performed, so that the luminance and chrominance signals are derived separately from the output terminals of the bridge circuit.
