Digital FM demodulation apparatus demodulating sampled digital FM modulated wave

摘要

The digital FM demodulation apparatus includes a sampling unit, a frequency specifying unit, and a demodulated value specifying unit. The sampling unit samples an FM modulated wave at predetermined intervals. The frequency specifying unit specifies a frequency of the FM modulated wave at the time of sampling based on a plurality of sampled values. The demodulated value specifying unit specifies a demodulated value corresponding to the frequency to provide the demodulated value.
