System for correcting an aural carrier signal

摘要

An aural carrier signal is corrected in a common amplifier system wherein the correction serves to reduce cross-modulation distortion of the aural carrier signal caused by non-linearities of the common amplifier system. An aural corrector receives a modulated visual carrier signal comprised of a visual carrier signal modulated by a video baseband signal and a phase corrected aural carrier signal and provides therefrom a combined corrected aural carrier signal. The visual carrier signal is combined with the combined corrected aural carrier signal to provide a corrected output carrier signal.
