Abstract
A Y/C separation circuit includes a first adder by which a carrier-multiplexed composite video signal is produced by multiplexing a color sub-carrier signal which is in synchronization with a color burst signal on a composite video signal during a vertical blanking period. The carrier-multiplexed composite video signal inputted to a 1H delay line and outputted from the 1H delay line. The carrier-multiplexed composite video signals at the input and the output of the 1H delay line are inputted to a second adder, and a subtracter, respectively. A luminance signal component and a chrominance signal component are respectively outputted from the second adder and the subtracter.
