Claims9
A frequency adjusting device comprising:
- a circuit board configured to determine and output a resonance frequency;
- and
- a frequency adjustor connected to at least one of a plurality of circuits mounted on the circuit board,
- wherein the plurality of circuits comprises:
- a first circuit configured to receive an input of an offset value from the frequency adjustor and output a pulse width modulation (PWM) signal;
- a second circuit configured to convert the PWM signal into an analog voltage;
- and
- a third circuit configured to generate the resonance frequency by using the analog voltage.
