PROBLEM TO BE SOLVED: To attain both improvement of the reception level of a communication signal and reduction in function deterioration of a processing circuit.SOLUTION: A communication device 1 generates a clock signal with an initial frequency F0 if the latest reception level of a communication signal exceeds a first reference level LA. If the latest reception level of the communication signal is the first reference level or below during generation of the clock signal with the initial frequency F0, the clock frequency of a clock signal to be generated is changed to a non-interference frequency F1 which does not interfere with the communication signal. Moreover, if the latest reception level of the communication signal is equal to or below a second reference level LB below the first reference level LA during generation of the clock signal with the non-interference frequency F1, the clock frequency of a clock signal to be generated is changed to the initial frequency F0. |
