Output power spectral densities for unipolar pulse frequency modulation with white noise input

Analysis of pulse-frequency-modulation (PFM) systems has already been carried out for the case of white Gaussian noise input and a resulting output consisting of a train of randomly-spaced unit impulses whose polarity was equally likely to be positive or negative. This note extends the analysis by deriving power spectral densities when the output impulse train is unipolar. System parameters are chosen to facilitate comparison with the earlier results
