    摘要: A digital FSK receiver includes a zero-crossing detector which detects the zero crossings in an FSK signal (FSK IN) having at least two frequencies. The time interval between zero crossings is then measured with a first interval value corresponding to one of the signal frequencies and a second interval value corresponding to the other signal frequency. An accumulator outputs a digital signal (RCVNR2) which depends on whether the interval is at the first value or the second value, the digital signal including logical zeros and ones.

    摘要: A digital FSK demodulator comprises a zero - crossing detector, and means for timing the intervals between zero crossings. The modulator comprises a phase accumulator, which is advanced by a variable amount, in dependance upon the data.
