Resumen:
The analytical spectrum of pulse width modulated
(PWM) signals with dead-time is derived in this paper. Previous
results were based on the double Fourier series expansion and
therefore they are only valid for a single tone modulating
signal. In this work analytical expressions for finite bandwidth
input signals are presented. Some simplifying assumptions are
considered to derive manageable expressions; however, extensions
to more general cases are straightforward. Theoretical results are
compared with computer simulations.
