ABSTRACT:
A receiver 700 having an audio output device 326 is disclosed. The receiver 700 receives a carrier signal modulated with data, voice, or a combination of both. The receiver 700 includes a demodulator 708 for demodulating the received carrier signal. The demodulated audio signal 302 is coupled to a delay circuit 300 where it is delayed and coupled to a detector 318. The detector 318 detects the presence of data or voice in the demodulated audio signal 302 and mutes or unmutes the audio output device 326 respectively. The delay circuit 300 stops any portion of the data signal to reach the audio output device 326.
