发明名称 METHOD OF REDUCING INTERFERENCE COMPONENTS IN A FREQUENCY MODULATED SIGNAL AND DEVICE FOR CARRYING OUT SAID METHOD
摘要 A method of reducing interference components in a frequency-modulated carrier signal in which the modulating signal contains a composite color television signal with a chrominance signal modulated on a chrominance subcarrier wave. In addition to the frequency modulation, the carrier signal is pulse-width modulated by the first-order lower side-band component of the frequency-modulated signal produced by the modulated chrominance subcarrier signal.
