Abstract
A first reproduced color under signal is delayed by one or two horizontal periods by a delay circuit, and this delayed second reproduced color under signal and the aforementioned first reproduced color under signal have their frequencies converted individually by first and second frequency converters into standard color signals. An oscillatory frequency signals of 2n of carriers for the aforementioned frequency conversions are divided to have the aforementioned carrier frequencies and to produce four carriers having phases of 0, 90, 180 and 270 degrees. These carriers are selectively fed to the first and second frequency converters by switches so that the two frequency-converted signals are subtracted or added in phase or in opposite phase to clear the noise (or crosstalk component), which is caused by the crosstalk between the tracks.
