Abstract:
A receiver of the present invention includes a microphone, an unnecessary signal remover, and an FM detector. The microphone receives a transmission signal generated by frequency modulating a signal in a frequency band that is receivable by the microphone, on the basis of transmission data. The unnecessary signal remover removes unnecessary signal components by processing the received signal from the microphone. The FM detector restores transmission data by performing FM detection of the received signal from which unnecessary signal components were removed by the unnecessary signal remover.
