From: Spectrum analysis of digital UPWM signals generated from random modulating signals
DFT spectra of UPWM signals generated from input signals with (a) truncated normal, (b) truncated Laplacian, (c) arcsine and (d) uniform distributions, evaluated for four (4) observation windows, \({d}_{1}=\frac{\text{44,100}}{{5}^{2}}=1764, {d}_{2}=\frac{\text{44,100}}{5}=8820, {d}_{3}=\text{44,100}, {d}_{4}=220,500=44,100.5\).
