するＦＭワイド受信機。In an FM wide receiver for receiving FM and TV audio broadcasts, a DC bias means for applying a DC bias to a path of an FM detection signal, a switch means provided between the path of the FM detection signal and the DC bias means; When the DC bias means is tuned to the reception band of TV audio broadcasting, V
It consists of a program counter that divides the frequency of the CO output, and a counting circuit that counts the output of the program counter every cycle and provides a bias output when the output exceeds a predetermined number. An FM wide receiver, characterized in that it is configured to turn off a switch element with a muting output when the output is below a set value.
