Abstract

PURPOSE:To achieve a picture with high separation degree, by separating an NTSC color television signal digitized into Y, I, Q signals through the processing of signals only on one horizontal scanning line and adding them to a comb type filter after multiplex on time axis. CONSTITUTION:A color television signal A digitized through sampling, e.g., in 14MHz is separated into Y, I, Q signals in 7MHz by using the signal on one horizontal scanning line at a separation circuit 21 to obtain a signal B in time division and multiplex via a multiplex circuit 22. A signal delayed by one horizontal scanning period with a delay circuit 24 and the multiplex signal B are added at an addition circuit 25 to output a multiplex signal D. Thus, the Y, I, Q signals are equal to be passed through in a comb type filter 23 respectively to achieve the picture with high separation degree and quality. Further, the comb type filter 23 can be of low speed operation type, allowing to economical constitution with small circuit scale.
