A Completely Integrated Monolithic Chroma Processing Circuit
Norman Doyle, D. Geoffrey Smith, A. Bugni, Russell E. Cushing · IEEE Transactions on Broadcast and Television Receivers · 1971
The NTSC color TV transmission system dictates that a receiver for that system must comprise the following basic elements for reproduction of the transmitted color information: * a chroma IF amplifier, to select and amplify the modulated color sub-carrier. * a sub-carrier regenerator, to furnish the required reference for demoduation of the suppressed carrier signal. * a chroma demodulator, to detect the information contained in the phase and amplitude modulation of the sub-carrier and turn it into signals suitable for driving a three-color, shadow-mask picture tube.
