In the M-AM receiver, the AM broadcasting and FM broadcasting are selected using a PLL synthesizer system, and the phase comparison circuit in the PLL and the low-pass filter that extracts the DC voltage from the comparison output of this phase comparison circuit are connected to the AM broadcasting. The DC voltage extracted from the low-pass filter is supplied to a voltage dividing circuit, and the first output voltage of this voltage dividing circuit is applied to the PLL circuit.
The second output voltage of the voltage dividing circuit is supplied to the FM broadcasting VCO in the PLL circuit as a control signal.
An FM-AM receiver that is supplied as a control signal to the above-mentioned VCO for AM broadcasting.
