Abstract
PFM demodulation which relies on the generation of one pulse per PFM signal period is compared with demodulation which generates two pulses per period. The dual pulse approach is shown to give an SNR advantage of up to 7 dB for the same input conditions, but the two methods give SNRs which converge when used to demodulate FM.
