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.
