    摘要: A demodulator includes a sampler configured to sample a plurality of first amplitude values of a modulated carrier signal using a constant sampling frequency and a plurality of second amplitude values of the modulated carrier signal at different times using the same constant sampling frequency. The constant sampling frequency is equal to a carrier frequency of the modulated carrier signal with a tolerance of +/−1% of the carrier frequency.

    摘要: A demodulator is provided for demodulating a phase-modulated data signal. The demodulator includes a phase frequency detector to output a voltage representing a phase difference between a received phase-modulated data signal and a reference clock signal. The voltage is input to first and second phase change detectors, which are provided to measure the phase difference of the phase-modulated data signal during first and second time periods, respectively.
