Abstract
Method and apparatus for comb filtering NTSC type television signals is described. The television signal is delayed by one line period, the delayed and the undelayed television signal are averaged. The resulting signal is delayed again by one line period and the delayed and the undelayed resulting signals are averaged, too. The result of the second averaging on the one hand is the luminance signal and on the other hand is subtracted by the television signal delayed by one line period. The result of such subtraction is the chrominance signal.
