PAL Color Picture Improvement Using Simple Analog Comb Filters

S. J. Auty, D. C. Read, G. D. Roe

Simple comb filters can be used to give better separation of luminance and chrominance in PAL decoders, thereby improving luminance resolution and reducing cross-color and cross-luminance. An important application is to decoders used by broadcasters, but the extra cost compared with a conventional decoder might be made low enough for such devices to be considered for domestic receivers. Cross-color can be reduced by using the principle in coders, and a suitable design is outlined.
