Conventionally, a clock recovery (clock reproduction) technique of recovering the clock signal from a received signal has been generally used in a receiving apparatus as a method of generating the clock signal required upon demodulation processing (for example, see Patent Document 1). FIG. 1 is a block diagram showing a main configuration of the receiving apparatus disclosed in Patent Document 1. In the receiving apparatus shown in FIG. 1, clock recovering circuit 13 recovers the clock signal from a received signal. The basic operation of clock recovery in clock recovering circuit 13 includes detecting points of level change of the received signal, controlling the frequency and phase of the clock signal held in clock recovering circuit 13 to synchronize with the detected points of level change and outputting the signal after control, as a recovered clock signal.
