Les cristaux ne s'appliquent pas aux :
- Amicrophones
- Bfiltres en treillis ("lattice filter")
- Coscillateurs
- Dfiltres actifs
Correct answer: D — filtres actifs. Question tirée de la banque officielle d'ISDE.
Why
Active filters use electronic parts like transistors and resistors to shape signals, relying on power to work, so they do not need the physical vibration of a crystal to function. The full explanation — and one for every question — is in Pro.
