<P>PROBLEM TO BE SOLVED: To provide a synchronous system in which a plurality of devices to be driven which need a timing signal for synchronization of a long period use commercial power to synchronize each other and operate. <P>SOLUTION: In this synchronous system, a power supply device 2 outputs to a radio base station device 3 power supply power subjected to omission processing about one cycle of commercial power waveform inputted through a power supply plug 1 by every predetermined commercial power period. The radio base station device 3 generates a frame timing signal on the basis of a part subjected to omission processing of output power of the power supply device 2. This realizes the synchronous system in which the plurality of devices to be driven which need the timing signal for synchronization of a long period use commercial power to synchronize each other and operate with the same power source. <P>COPYRIGHT: (C)2004,JPO |
