Abstract

PURPOSE:To perform wireless connection to an audio device by detecting automatically stereophonic, monaural and double sound of the sound signal, which is multiplexed to a TV signal, and by subjecting and stereophonic demodulation signal to FM stereophonic modulation again and re-transmitting this modulated signal. CONSTITUTION:The pilot signal output of band-pass filter 5 is amplified by 55.125kHz amplifier 12 and is detected by AM detector 13. The pilot signal of composite sound signals is taken out by 922.5Hz reed filter 14 and 982.5Hz reed filter 15, and stereophonic, monaural and double sound are detected and switched automatically by automatic signal switching circuit 18. The stereophonic demodulation output is taken out from line-out terminals b and c through selector switches 10 and 11 and low-pass filters 19 and 20. The stereophonic demodulation output is applied to stereophonic modulator 23 through 50mu pre-emphasis circuits 21 and 22 and is subjected to stereophonic modulation, and after that, this output is modulated and amplified by FM modulation transmitter 27 and is transmitted by antenna 29.
