<P>PROBLEM TO BE SOLVED: To provide a control method for a radio communication device and the radio communication device in which the followup performance and noise suppression performance of a control circuit including filtering processing are improved by changing the time constant of the filtering processing dynamically in accordance with an environment in simple configuration. <P>SOLUTION: A plurality of filters (110 and 120) having different time constants are provided, the difference of outputs from the plurality of filters (110 and 120) is compared with a preset threshold in a differential circuit 130 and on the basis of the compared output, a selector circuit 140 selects any one of the outputs from the plurality of filters (110 and 120). <P>COPYRIGHT: (C)2003,JPO |
