<P>PROBLEM TO BE SOLVED: To prevent an erroneous fading frequency from being detected when a received channel is switched. <P>SOLUTION: Fading correction steps 93b, 99b for receiving outputs of fading detection steps 93a, 99a and a selection signal are provided. When the selection signal is changed, the fading correction steps 93b, 99b correct output values of the fading correction steps 93a, 99a calculated at channels before the change depending on a difference from the channels, and consequently, the fading frequency can be detected with high accuracy even when the received channel is switched. <P>COPYRIGHT: (C)2007,JPO&INPIT |
