て成るＦＭ送受信機。 In an FM transmitting/receiving circuit that uses a shared antenna for transmitting and receiving and simultaneously transmits and receives in different frequency bands, the minimum S is required to perform mute operation with hysteresis characteristics and to achieve good reception.
/N comprises a mute circuit whose mute sensitivity is set to perform a mute operation at a higher sensitivity than the mute sensitivity, and a ringing means whose ringing tone generation sensitivity is set so as to emit a ringing tone at a sensitivity higher than the mute sensitivity. FM transmitter/receiver.
