FSK DDC Non-coherent demodulation is usually used for FSK signal,where narrowband filter with good selectivity is necessary for extraction of both signal enveloping and timing.The comb-spectrum IIR filter is used here.In this paper,an introduction is given about the implementation principle of the all digital 2FSK demodulator,with an emphasis on the technology scheme of the infinitely circular comb- spectrum filter used for the extraction of signal enveloping and timing,whose practicality has already been validated in many projects.
