Quel genre d'adaptateur favorise le plus la suppression d'harmoniques?
- AL'adaptateur en pi inversé
- BL'adaptateur en pi
- CL'adaptateur L
- DL'adaptateur pi-L
Correct answer: D — L'adaptateur pi-L. Question tirée de la banque officielle d'ISDE.
Why
A Pi-L network adds an extra inductor and capacitor to the standard Pi shape, creating a steeper filter that blocks unwanted harmonic signals more effectively than simpler designs. The full explanation — and one for every question — is in Pro.
