<p>In a receiving device, an intermediate frequency component of a received broadcast radio wave is allowed to selectively pass through an intermediate frequency filter (304), and part of it is output to a narrow-band filter (306), the remaining is amplified at an intermediate frequency amplifying unit (305) to be output to an ARC unit (309). The narrow-band filter (306) allows, out of the intermediate frequency components, a component derived from the desired station radio wave to selectively pass. Then, the electric field intensity of the component derived from the desired station radio wave is detected at a detecting unit (308), and a detection result is output to the ARC unit (309).</p> |
