<p>PURPOSE:To prevent a clock from getting out of a cycle at the time of switching a receiving system by selecting demodulating data corresponding to the reception levels of respective receivers, supplying a demodulating clock from one of the receivers to a clock generating circuit and generating a reproducing clock and a system clock. CONSTITUTION:When a selecting switch 6 is changed over by a select signal, the demodulating data from a receiver 21 or 22 at the higher reception level are selected and outputted as select data so that the effect of diversity can not be damaged. Since a clock inputted to a clock generating circuit 5 is fixedly supplied to from the receiver 21, however, the phase is not changed at the switching point of the select signal even when the receiving system is switched by the diversity. Therefore, even when the reception levels of the respective receivers 21 and 22 are changed for each bit and the receiving system is frequently switched, the phase of the clock does not jump in the circuit 5, and a reproducing clock 7 and the system clock are normally generated.</p> |
