Abstract
In a color decoder for a color television receiver, including a demodulator for demodulating a modulated chrominance subcarrier to obtain color signals, delay lines in the form of a charge storage and transfer circuit for delaying the color signals by one picture line scanning period, and adder stages forming a matrix connected to produce color difference signals from the delayed and the undelayed color signals, the demodulator and the adder stages are constituted by integrated charge storage and transfer circuits on a semiconductor chip.
