Abstract
PURPOSE:To make the titled device suitable for an integration and inexpensive by sharing a CCD delay circuit to remove a stroke and a 1H delay circuit to remove the interference of a flyback pulse to a pilot signal. CONSTITUTION:The output of a second balanced modulator BM6 is the one that the output of a first BM5 is delayed by only 1H and by subtracting the output of the second BM6 from the output of first BM5 by a subtracter 7, the stroke can be removed. On the other hand, the output of a 1H delay circuit 4 is subtracted from the output of an automatic color adjusting circuit ACC3, the interference of the flyback pulse is removed and by passing through a band- pass filter BPF27, a reproducing pilot signal can be obtained. Here, since the 1H delay circuit 4 is the one that delays a low-area converting chrominance signal which is at the level of fs+ or -500kHz and the pilot signal lower than that, the CCD delay circuit having a lower sampling frequency and a smaller capacity can be realized as compared with the time of delaying a carrier chrominance signal Thus, an inexpensive chrominance signal processing circuit suitable for the integration can be realized.
