摘要
In the transmission of a color television signal containing chrominance burst and sync signals over a Nyquist channel between a transmitting station and a receiving station, a method for modulating and synchronously demodulating the television signal according to the offset modulation and offset sampling principle. The chrominance burst or sync pulses are used as a reference signal for frequency recovery at the receiving station. An additional reference signal is generated at the transmitting station and transmitted over the Nyquist channel. The additional reference signal is utilized for phase recovery at the receiving station.
