From: Spectrum analysis of digital UPWM signals generated from random modulating signals
DFT coefficients (in dB) of the even carrier harmonics of five UPWM signals generated by an equal number of random input signals whose samples follow Pearson distributions with parameters \({\mu }_{x}=0, {\sigma }_{x}=1, {\mu }_{x,4}=3\) and \({\mu }_{x,3}=0.2, 0.4, 0.6, 0.8, 1\).
