とを特徴とするＴＶ・ＦＭ受信機。 FM broadcast and TV with a single front-end circuit
In a TV/FM receiver capable of receiving broadcasts, the output of the local oscillator of the front end is transmitted to the FM receiver.
It is equipped with a means that can distinguish and detect a band corresponding to broadcasting and a band corresponding to the TV broadcasting, and the detection output is used to connect the TV demodulation system and FM after the detection output.
A TV/FM receiver characterized by being able to switch between two transmission systems: a demodulation system and a demodulation system.
