Abstract

Se proporciona un procesador de senal (30). El procesador de senal está configurado para recibir una primera senal analogica y convertir la primera senal analogica en una senal digital. La senal digital se transmite a través de una barrera eléctrica y se convierte en una senal de modulacion por ancho de pulso ajustada a escala. La senal de modulacion por ancho de pulso ajustada a escala se convierte luego en una segunda senal analogica ajustada a escala, a la que le da salida el procesador de senal (30).
