  • Patent number: 4493102
    Abstract: System for routing stereo radio frequency signals over alternate audio channels in response to detection of an interference in one of the stereo signals. The system delays the radio signals during which time it detects whether an interference has corrupted one of the radio signals. If a corruption has occured, the system switches the non-corrupted signal to an active one of the audio channels so that the interference is prevented from being reproduced prior to reaching an audio output.
