<p><P>PROBLEM TO BE SOLVED: To securely demodulate a modulated signal even in the case that a part of the modulated signal is not detected. <P>SOLUTION: An antenna unit 21 receives the modulated signal in which a carrier wave is subjected to amplitude modulation by transmission data. Then a diode detector 101 demodulates the received modulated signal by envelope detection. The present invention can be applied to, for example, a non-contact IC card, a reader/writer, etc. as an information processing apparatus for demodulating the modulated signal in which the carrier wave is subjected to the amplitude modulation by the transmission data. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
