A Method of Directly Demodulating Color Signals
Norman W. Parker, Francis H. Hilbert · IEEE Transactions on Broadcast and Television Receivers · 1967
Color TV signal evolution is examined from a sampling encoder (modulator) viewpoint. This logically leads to an analysis of decoding (demodulating) the NTSC color signal with sampling techniques. In the process of enumerating and solving the problems that arise by attempting to demodulate by time - interruption of the signal, basic concepts relating to direct demodulation of the NTSC signal are derived.
