Abstract
A signal processing circuit achieves a wide display mode without switching on and off an S correction in a horizontal deflecting system, and includes digital memories 16a, 16b and 16c for receiving a luminance signal Y, a color difference signal B-Y and a color difference signal R-Y. The writing operation of each digital memory is controlled by a sampling clock f.sub.CW of a write control circuit 18, and the reading operation of each digital memory is controlled by a sampling clock f.sub.CR of a read control circuit 19. A clock oscillator 24 of the read control circuit 19 produces the sampling clock f.sub.CR whose frequency is varied in accordance with a modulation voltage of a modulation voltage generator 31 in each line interval.
