Abstract
PURPOSE: To realize easily the sound multiplication even for the TV picture receiver which has no connection terminal by securing the inductive connection of the pickup circuit to the output of the SIF circuit of the TV picture receiver.
CONSTITUTION: For the general home-use TV picture receiver, the resonance detection is given to the SIF frequency of 4.5MHz at pickup circuit 11 with amplification 12, and the output nearly identical to SIF circuit 4 is obtained at SIF circuit 13 to carry out sound detection 14. Sound detection circuit 14 features a wider band than sound detection circuit 5 of the TV picture receiver and thus can detect up to pilot carrier 55.125kHz, and sound subcarrier 31.5kHz in the detection output receives secondary sound amplification 15 to be demodulated at secondary sound detection circuit 16. At the same time, the pilot carrier is amplified 17 and then demodulated at control signal decision circuit 18. Then each signal of circuits 14, 16 and 18 is supplied to matrix circuit 19 to obtain the stereo signals.
