Abstract

A microprocessor controlled color phase locked loop is provided which provides flexibility and adaptability for different television standards and sampling rates. Color burst phase error and color burst amplitude information are stored in data registers located at the output of the phase locked loop's low pass filter rather than at the output of the color demodulator.
