Benefits of feedback:
A. Performance of system is greater.
B. Need for system much larger path gain and system instability.
C. Controlled variable accurately follows the desired value
D. Affected by parameter variations
Answer:D
Benefits of feedback:
A. Performance of system is greater. B. Need for system much larger path gain and system instability. C. Controlled variable accurately follows the desired value D. Affected by parameter variations
Explanation: Closed loop system is the system with the feedback and this can be positive or negative feedback and having feedback have less dependence on parameter variation.
