What are the distinguishing features of a Chebyshev filter?
- A It allows ripple in the passband in return for steeper skirts
- B It requires only inductors
- C It requires only capacitors
- D It has a maximally flat response in the passband
Correct answer: A — 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 a sharper cutoff, meaning it intentionally lets the signal strength wiggle, or ripple, inside the passband to achieve much steeper sides, known as skirts, that block unwanted frequencies more effectively.
