The first gate circuit receives a composite color signal consisting of chrominance signals and burst signals which are arranged alternately and then extracts the chrominance signals and burst signals from the composite color signal. The extracted chrominance signal is amplified by the chrominance signal amplifier, while the phases of the extracted burst signal is controlled by the hue control circuit. The outputs of the chrominance signal amplifier and the hue control circuit are added by said reproducing means, thereby reproducing a composite color signal. The AC coupling capacitor is coupled to the output of said means. The second gate circuit extracts from the output of the AC coupling capacitor chrominance signals and burst signals. | |
