Abstract
A color signal reproducing circuit having A/D converter , sync separator , YC separator , gain controller , multipliers and , low-pass filters and , burst-period cumulative adders and , SINCOS generator , clock generator , and ramp-wave generator . The simple structure allows a color signal reproducing circuit to be used commonly in a different television systems without changing its clock frequency considerably in accordance with broadcasting systems and also achieves YC separation and color signal demodulation from analog composite signal with a higher degree of precision.
