The frequency response shown in the figure below belongs to which of the following filters?
A. Type-1 chebyshev
B. Type-2 chebyshev
C. Butterworth
D. Elliptical
Answer:A
The frequency response shown in the figure below belongs to which of the following filters?
A. Type-1 chebyshev B. Type-2 chebyshev C. Butterworth D. Elliptical
Explanation: Since the pass band is monotonic in behavior and the stop band exhibit equi-ripple behavior, it is the magnitude square response of a type-2 chebyshev filter.
