Abstract: An error detector determines whether or not there is a frequency error. In a case where it is determined that there is the frequency error, the error detector further determines whether or not the frequency error stays within a targeted error range. In a case where it is determined that the frequency error stays within the targeted error range, a proportional gain is decreased. In a case where it is determined that the frequency error fails to stay within the targeted error range, the proportional gain is increased. Then, a frequency proportional-integral-derivative operation processing is executed based on a set gain.
