What is the primary advantage of the Butterworth filter over the 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 maximally flat response over its passband
Correct answer: D — It has maximally flat response over its passband. From the official ISED question bank, verified word for word.
Why
A Butterworth filter is designed so that the signal strength stays perfectly steady across the frequencies it lets through, creating a smooth curve with no bumps or dips. The full explanation — and one for every question — is in Pro.
