Abstract

PURPOSE:To make a postable radio apparatus small-sized and light, by changing and switching the timing for generating a clock signal, by a prescribed phase difference, in case when a phase shift has been detected. CONSTITUTION:A clock generating part 16 operates independently in the receiving side, and generates a clock signal for sampling a receiving digital signal, having prescribed pulse width. A phase difference detecting part 9 detects a phase shift by detecting the overlapping of the prescribed pulse width of the clock signal, and the conversion point of the receiving digital signal. In case when this phase difference detecting part 9 has detected a phase shift, the timing for generating the clock signal in the clock generating part 16 is changed and switched by a prescribed phase difference.
