- Cauer filter
- Butterworth filter
- Chebyshev filter
- Band-reject filter
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Butterworth filter is known as a "flat-flat" filter because it has a maximally flat frequency response in the passband, meaning it has no ripples in the passband, providing the smoothest possible response.
Thus, the correct answer is Butterworth filter.
