Also, when the input signal disappears, the output signal of the input signal detection circuit 7 goes to an L level. Then, a switch 8 is activated, and a constant voltage from the constant voltage generator 9 is applied on the input terminal of the voltage controlled oscillator 5, and the signal with stable frequency can be obtained from an output terminal 10.
