A frequency adjusting method comprises steps of: generating a first adjusting signal according to a frequency of a first output signal; adjusting a frequency of an input signal by using the first adjusting signal to generate the first output signal, so as to adjust the frequency of the first output signal into a first range; generating a second adjusting signal according to a frequency of a second output signal; adjusting the frequency of the first output signal by using the second adjusting signal to generate the second output signal, so as to adjust the frequency of the second output signal into a second range; and adjusting the first adjusting signal and the second adjusting signal according to the second adjusting signal. |
