<P>PROBLEM TO BE SOLVED: To effectively reduce noise on receiving AM (amplitude modulation) with a simple structure. <P>SOLUTION: An AM receiver 100 comprises an AM detector 101, an FM detector 102, and an adaptive filter 105. The AM detector 101 performs AM detection on reception signals including AM signals. The FM detector 102 performs FM detection on the reception signals. The adaptive filter 105 performs processing on the input signals detected by the AM detector 101 by reference signals based on the signals detected by the FM detector 102, and outputs the processed signals as audio signals. <P>COPYRIGHT: (C)2013,JPO&INPIT |
