Abstract
A color signal demodulation apparatus includes an A/D converter for converting a composite color television signal into a digital signal, a pulse generator for generating timing pulses and sampling clocks, a Y/C separator for separating the output from the A/D converter into a luminance signal and a carrier chrominance signal, a subcarrier generator for detecting the phase of the subcarrier from the color burst signal, and a color signal demodulator for obtaining baseband color signals. The apparatus of the invention requires no low-pass filter.
