Comment appelle-t-on le circuit qui emploie un convertisseur analogique à numérique, un système de transformation mathématique, un convertisseur numérique à analogique et un filtre passe-bas?
- AUn transformateur mathématique
- BUn transformateur numérique
- CUn processeur de signal numérique
- DUn formateur numérique
Correct answer: C — Un processeur de signal numérique. Question tirée de la banque officielle d'ISDE.
Why
A Digital signal processor is the correct term because it describes a system that converts real-world analog signals into digital numbers, applies mathematical changes to those numbers, and then converts them back to analog form for further use. The full explanation — and one for every question — is in Pro.
