Abstract

PURPOSE:To enable to receive FM radio broadcast, by taking the intermediate frequeny at FM reception to the 2nd voice intermediate frequency and connecting the output of tuner to the 2nd voice intermediate amplifier of television at FM reception. CONSTITUTION:At FM reception, TV high-band power supply terminal VH and TV low-band power supply terminal VL are both taken at around -15 volts. Further, all swtiching diodes 27, 28, 29, 30, 46, 47, 52, 53, 62, 63 and 7 are off. Further, the FM intermedaite frequency signal appeared at the output terminal 18 via a mixing circuit 16 and a low-pass filter 17 is 4.5MHz being the television 2nd voice intemediate freuqnecy.
