TLDR
In this paper, a monolithic integrated circuit which performs the subcarrier regeneration task in a color television receiver is described, which involves time-sharing and current switching techniques, and an in-phase detector for color killing and chroma AGC.Abstract:
A monolithic integrated circuit which performs the subcarrier regeneration task in a color television receiver is described. Differential amplifier configurations are used in a novel circuit concept which involves time-sharing and current switching techniques. The result is a realization of the design objectives with a relatively simple structure. The burst gate, phase detector and voltage controlled oscillator functions called for by the classical APC loop are provided. In addition, an in-phase detector for color killing and chroma AGC is included, as well as a novel DC controlled hue adjustment.read more

A Monolithic Chroma Demodulator Integrated Circuit for Color Television Receivers
TL;DR: Early color demodulators were described and analyzed as narrow angle sampling devices as mentioned in this paper, and luminance as well as chrominance was applied to the demodulator since proper operation required primary color signal outputs.
