摘要：An amplifier circuit that amplifies a carrier wave that a transmitting and receivingpart has received, and includes a superimposition wave generation part that generates asuperimposition wave to be superimposed onto the carrier wave; an amplifying part thatadds the carrier wave and the superimposition wave to obtain an amplified carrier waveand outputs the amplified carrier wave; and an amplitude detection part that detects,based on a change in an amplitude value of the carrier wave, that the carrier wave is apredetermined carrier wave that carries a predetermined communication signal. Theamplifier circuit outputs the amplified carrier wave when having detected thepredetermined carrier wave.
