    摘要： A method and apparatus for demodulating an input signal, for example, in a communications system, is disclosed. The apparatus includes a signal preconditioner and a demodulator. The signal preconditioner may include a low-pass filter and a hysteretic comparator that are configured to precondition a preconditioner input signal to provide a preconditioner output signal. The modulator may be configured to demodulate the preconditioner output signal.
