Abstract
A cross-talk suppression circuit is disclosed for use in an optical communications system which employs a light-emitting diode. A video signal and an audio-modulated carrier signal are both coupled to the light-emitting diode. A cross-talk reducing circuit is provided to couple the audio-modulated carrier signal to the light-emitting diode. The circuit comprises a voltage-controlled phase shifter for coupling the audio-modulated carrier signal to the light emitting diode, the phase shifter having a phase shift that is controlled by the video signal.
