What is the primary advantage of the Chebyshev filter over the Butterworth filter?
- A It has maximally flat response over the passband
- B It allows ripple in the passband in return for steeper skirts
- C It requires only capacitors
- D It requires only inductors
Correct answer: B — It allows ripple in the passband in return for steeper skirts. From the official ISED question bank, verified word for word.
Why
A Chebyshev filter trades a perfectly smooth signal for sharper cutoffs by intentionally letting the signal strength wiggle slightly within the passband, which creates steeper skirts that block unwanted frequencies more effectively. The full explanation — and one for every question — is in Pro.
