RE: FDA Morphosis

Gérard, malheureusement non, tu n'obtiendras jamais 120 dB avec une carte son. En fait la seule limitation pour obtenir de telles niveaux de linéarité avec le numérique est la stabilité d'horloge. Les DDS sont ultra performants, mais limités par le bruit d'horloge.

Audio pavillon, je ne connais pas d'ampli class-D sans filtre passe bas. Mais il suffirait de faire le test en l'enlevant pour voir si j'ai raison ou non.
Concernant la conversion PCM/PWM, personnellement je te fais le convertisseur en 3 minutes chrono dans un FPGA avec une linéarité supérieure à 0,001%. Encore une fois la seule contrainte c'est les horloges non synchrones. Mais si mon horloge de sortie est strictement multiple entière de mon horloge d'entrée, alors je n'aurai aucune distorsion dans la conversion.
