Abstract
Circuit arrangement for separating the components of a PAL color television signal, in which the (digitized) u- and v-signals of the subcarrier frequency are passed through two delay lines which produce different time delays (for example 283.5 and 284 chrominance subcarrier periods): an improved cross-talk attenuation from the luminance signal to the chrominance signals in the lower sideband is then obtained.
