Detailed Solution: Question 4
Consider the following statements:
1. Closed loop system is less sensitive to variations in feedback path parameters than variations in forward path parameters.
2. Feedback can improve the stability or may be harmful to stability if it is not properly designed and applied.
3. Feedback controls the time response of the system by adjusting the location of poles.
Q. Which of the these statements are correct?
1. Closed loop system is less sensitive to variations in feedback path parameters than variations in forward path parameters.
2. Feedback can improve the stability or may be harmful to stability if it is not properly designed and applied.

The open loop transfer function of this system is
The open loop transfer function of this system isDetailed Solution: Question 7
Assertion (A): Feedback in control system improves the time response of the system.
Reason (R): Time constant of an open loop system is less than the time constant of a closed loop system.
Reason (R): Time constant of an open loop system is less than the time constant of a closed loop system.
