Quelle expression est en fait le rapport en décibels entre le signal maximal admissible (reproduit sans distorsion audible) et le signal minimal détectable (sensibilité) à l'entrée d'un récepteur?
- ALe paramètre de conception
- BLa stabilité
- CLe facteur de bruit ("noise figure")
- DLa gamme dynamique
Correct answer: D — La gamme dynamique. Question tirée de la banque officielle d'ISDE.
Why
Dynamic range measures the span between the faintest signal a receiver can hear and the loudest signal it can handle before distorting, essentially defining how well the radio copes with both weak and strong stations at once. The full explanation — and one for every question — is in Pro.
