Aural carrier correction system and method.

摘要

A system and method reduce unwanted aural carrier modulation caused by the visual signal in a common amplification television transmitter which amplifies both an aural signal and the visual signal simultaneously. A non-linear amplitude domain video signal and a non-linear phase domain video signal respectively amplitude and phase modulate the aural signal to generate a modified aural signal. A non-linear amplifier is used to generate the non-linear amplitude domain video signal and the non-linear phase domain video signal which respectively having amplitude and phase components that are directly opposite to unwanted amplitude and phase components added to the aural signal by the visual signal. <IMAGE>
