ENG:
A simple switching amplifier, however the L.P. filter doesn't work.
The audio input is converted in a digital format (1 and 0) with an op-amp (comparator) and a sawtooth-signal generator.
After, the "PCM" audio is amplified by another stage and at the end a Low Pass Filter convert the digital stream in an analog stream.

ITA:
Un semplice amplificatore switching, però il filtro passa-basso non funziona.
L' audio in ingresso viene convertito in un formato digitale (1 e 0) con un op-amp (comparatore) e un generatore di segnale a dente di sega.
Dopo, il segnale di tipo "PCM' viene amplificato da un' altro stadio e alla fine esce da un filtro passa basso che converte il formato digitale nuovamente in un formato analogico adatto ai diffusori.
