Optimal digital audio amplifier
Author: Polášek Vojtěch
This work deals with the problem of calculating the digital audio amplifiers. First,
there is discussed the calculation of frequency spectrum odd extended signal range of
general signal, then there is shown a way to determine the switching times of the PWM
signal from the spectrum. Furthermore, it dismantled the problem of calculating for too
long signal, divided into shorter parts and connecting sub PWM signals. Finally, this
procedure is implemented to function in the Mathematica system and tested for a short
audio recording.
