Abstract
A device of one aspect of the present invention includes a receiver to receive a modulation signal that has been subjected to frequency shift keying division ratio. The receiver includes a first demodulator and a demodulation control signal generator. The demodulation control signal generator includes a first frequency divider, a frequency control signal generator, and an oscillator. The first frequency divider divides a frequency of one of the modulation signal and the demodulation control signal by a first or second reception division ratio. The frequency control signal generator generates a frequency control signal based on a frequency of the other of the modulation signal and the demodulation control signal, and a frequency of the one of the modulation signal and the demodulation control signal obtained by division by the first or second reception division ratio. The oscillator generates the demodulation control signal based on the frequency control signal.
