Abstract
A signal-to-noise ratio improving circuit for a color video signal comprises an adder supplied with a chrominance signal of an input color video signal, a delay circuit supplied with an output signal of the adder, for delaying the signal supplied thereto by a delay period which is in terms of one horizontal scanning period of the input color video signal and producing an output signal to the adder wherein the output signal of the delay circuit is added with the input chrominance signal, and a switching circuit supplied with the input chrominance signal and the output signal of the adder. The switching circuit passes the output signal of the adder during an interval corresponding to a color burst signal of the input chrominance signal and passes the input chrominance signal during intervals other than the color burst signal interval of the input chrominance signal.
