Abstract
A chroma-burst separator and amplifier suitable for use in the chrominance channel of a color television receiver includes a differential amplifier for supplying antiphase composite chrominance signals including burst and chroma signal components to first and second gating circuits, respectively. The first and second gating circuits conduct in complementary fashion in response to keying pulses coincident with the burst and chroma signal intervals for providing separated antiphase burst and antiphase chroma output signals each with differential direct potentials which remain substantially constant and equal throughout the chroma and burst intervals.
