Abstract: The determination of the frequency spectrum of a pulse width modulated (PWM) signal with general band-limited input x(t) has been an open problem for many years. We describe a new approach that gives exact analytical expressions for the spectra of uniform-sampling PWM signals and natural-sampling PWM signals with single-edge as well as with doubleedge modulation. For the special case of single tone modulating signals, our results reduce to those obtained previously using a double Fourier series ... (Update)

...Consider a PWM process with arbitrary input signal ####, limited in range to # #. The analysis given here is summarized from [16]. While any PWM approach can be modeled, we will consider trailing edge, single sided modulation (TEPWM) in this paper. The results are extended...
