摘要

"System to reduce intermittent interruptions in a broadcasting system processes audio, to reduce interruptions in an intermittent broadcasting of audio.For broadcasting in band on channel, and to receive a broadcast signal, receiving a broadcast signal, and transmitter broadcasting in band on channel ".A system (100) to minimize interruptions in an intermittent audio broadcasting system is provided in which a primary radio signal and a redundant radio signal are transmitted from a suB - system transmitter (120) and received by a receiver subsystem (140).The output (112) of a radio source (110) is coupled to a modulator (160) to modulate a signal radiofrequ00b3u00eancia (162) for attaching to a transmitting antenna (172).A second output (114) of the audio source (110) is coupled to a delay circuit (116) to add a predetermined time delay.The signal from the audio source late is attached to a modulator (164) for modulating a second signal of radiofrequ00b3u00eancia (166) that is also coupled to the transmitting antenna (172).The sub receiver system (140) receives both the primary radio signal and a radio signal redundant late and engages each a respective demodulator (180, 182).At least demodulator (180) includes a circuit (181) to determine the degradation in primary radio signal and provides an output signal for measuring quality (186) to a control circuit of M.Istura (190).The primary audio signal recovered from the demodulator (180) is coupled to a second circuit delay (184).The delay time of the second delay circuit (184) being substantially equal to the delay time of the delay circuit (116).The audio output of the delay circuit (184) and the audio output of the demodulator redundant (182) are coupled to a sub mixing system (135).In which each is combined with a weighting factor and then combined together to form a composite audio signal for coupling to the audio output circuit (150).
