A differentiator is usually not a part of a control system because it
A. Reduces damping
B. Reduces the gain margin
C. Increases input noise
D. Increases error
Answer:C
A differentiator is usually not a part of a control system because it
A. Reduces damping B. Reduces the gain margin C. Increases input noise D. Increases error
Explanation: A differentiator is generally not the part of the control system as it increases the input noise due to reduced gain and increased bandwidth.
