ABSTRACT:
A color signal reproducing circuit comprising a phase correction device receiving a gain-controlled composite color signal, detecting color burst signal in a composite color signal and correcting phase of the color burst signal by using a 3.58 MHz signal, first gate for receiving the gain-controlled composite color signal and passing only a color signal when a color burst pulse in the delayed horizontal synchronizing signal applied from the delay device is at a low level, and mixer for mixing the phase-corrected color burst signal and the color signal from the first gate to produce a phase-corrected composite color signal.
