摘要：
A receiver of a frequency-modulated signal representing a digital signal includes a down conversion unit or frequency translation unit to lower the frequency of the frequency-modulated signal and a digital demodulator to regenerate the digital signal from the lowered-frequency signal. The receiver furthermore includes a counter circuit to determine the number of periods of a reference signal from the frequency translation unit during a period of the lowered-frequency signal. The digital demodulator includes a computer unit to compute the period of the lowered-frequency signal from the number of periods of the reference signal.
