<P>PROBLEM TO BE SOLVED: To provide a receiver capable of preventing deterioration in the reception characteristic and stably operating the reception. <P>SOLUTION: The receiver including: analog signal processing sections (2, 3, 5) for applying band limit, amplification, and frequency conversion to a received radio frequency signal; A/D conversion sections (11-1, 11-2) for converting signals from the analog signal processing sections into digital signals; functions (14, 15, 12-1, 12-2, 7-1, 7-2) for detecting and correcting DC offset of an input signal; AGC functions (17, 18, 19, 10-1, 10-2) for detecting the level of the input signal to keep the level to a prescribed level; and a signal processing section (16) for processing the digital signals, is characterized in that filters are inserted when performing the input detection in the AGC functions to eliminate a DC component and a power level of the input signal is detected to apply AGC control to the power level. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
