Quel type de filtre a des ondulations dans la bande passante et une pente abrupte?
- ALe filtre Butterworth
- BLe filtre Tchebychev
- CLe filtre actif LC
- DLe filtre passif à amplificateur opérationnel
Correct answer: B — Le filtre Tchebychev. Question tirée de la banque officielle d'ISDE.
Why
A Chebyshev filter is the right choice because it is specifically designed to trade a smooth signal for a faster drop-off, creating small ripples (wiggles) in the passband while achieving a very sharp cutoff to block unwanted frequencies. The full explanation — and one for every question — is in Pro.
