Abstract
A digital wireless receiving apparatus performs AGC control. A desired wave level is detected at a modulator, and AGC control is performed for a high frequency portion by detecting a desired wave level at a demodulator. A tap number of a digital filter in the demodulator is controlled or another analog filter of an intermediate frequency detects an input level of an interfering wave or a desired wave, thereby performing AGC control for the high frequency portion and controlling the tap number of the digital filter at the demodulator.
