Hola otra vez

Investigando sobre el tema encontre lo siguiente en http://www.powersoft.it/a_prod.html
Entrar en la liga de DIGRAM series

Output stage: the principle of conversion
DIGAM products are based on PWM technology, that has been used for 30 years or more in power supplies and inverters. PWM provides high reliability, small size, low weight and high efficiency. A PWM converter works as a high frequency sampler, converting the variable amplitude (audio) signal into an impulse sequence with average value equal to the audio input. DIGAM amplifiers use very high sampling frequencies to obtain high performances across the audio band. The PWM digital signal is amplified by very fast solid state power switches and it is then demodulated by an output power filter. Powersoft S.r.l. holds several patents on the switching technology and the output demodulating filter.

Lo cual refuerza mi idea ya expuestas.
