Abstract
A network combines luminance and chrominance signals to provide a composite video signal wherein the chrominance signal is subjected to band pass filtering to reject low frequency noise and the luminance signal is subjected to filtering by a predetermined amount at the color subcarrier frequency to reject color dots. In a preferred implementation, the filter is realized with only one inductor and one capacitor thereby preventing displayed artifacts with the economic and reliability benefits of minimal parts count.
