With negative feedback in a closed loop control system, the system sensitivity to parameter variation:
A. Increases
B. Decreases
C. Becomes zero
D. Becomes infinite
Answer:B
With negative feedback in a closed loop control system, the system sensitivity to parameter variation:
A. Increases B. Decreases C. Becomes zero D. Becomes infinite
Explanation: Sensitivity is defined as the change in the output with respect to the change in the input and due to negative feedback reduces by a factor of 1/ (1+GH).
