変えることを特徴とするＦＳＸ信号発生器。[Claims for Utility Model Registration] The voltage of power source 1 is divided by resistor 2, this divided voltage A is applied to switch 3, the voltage of power source 1 is divided by resistor 4, and this divided voltage B is applied to switch 5. In addition, a digital signal consisting of "1" and "0" is input to the input terminal 6, and the said signal becomes "
1", the switch 3 is closed and the voltage A is set to vco.
In addition to 7, when the signal is ``0'', the inverter 8 inverts the signal to ``1'', closes the switch 5, applies the voltage B to VCO 7, and converts the signal to ``1'' and ``0''. In the FSK signal generator that changes the oscillation frequency of the VCO 7 correspondingly, a switch 11 is provided between the input terminal 6 and the connection point 9, the input terminal 6 is connected to the switching terminal 11A of the switch 11, and the switching terminal 11B of the switch 11 is connected to the switching terminal 11A of the switch 11. When the switch 12 is connected to the switching terminal 12A, "0" is input to the switching terminal 12A of the switch 12, "l" is input to the switching terminal 12B of the switch 12, and the switch 11 is connected to the switching terminal 11A, the input terminal 6 is input. The FSX signal generator is characterized in that the oscillation frequency of the VCO 7 is changed by the signal, and when the switch 11 is connected to the switching terminal 11B, the oscillation frequency of the VCO 7 is individually changed by switching the switch 12.
