Abstract
A frame-to-frame comb filter for separating chrominance and luminance signals from composite video signals produces objectionable double images around the edges of moving objects. The double images are substantially removed by low pass filtering the combed chrominance signal and combining the low pass filtered chrominamce signal with the combed luminance signal.
