Specification

To generate the PWM signal we have to compare the sinewave signal (tone) and a signal sawtooth signal whitch be generate with the counter.

The block diagram is:

With the block which has in entry (in put: PWM_out) and (output: C0, C1) we are going to get back the whole signal PWM_out.

The simulation is described in following figure:
