Read Time:1 Minute, 31 Second

This set of Control Systems Multiple Choice Questions & Answers (MCQs) focuses on “Linearizing Effect and Regenerative Feedback”.

1. The relation between output response and input signal in closed loop system is :
a) Exponential
b) Parabolic
c) Linear
d) Nonlinear

2. Assertion (A): Practical systems must be closed loop system.
Reason (R): This is due to the fact that closed loop systems are least affected by parameter variations, stable, higher bandwidth, linear and more speed of response.
a) Both A and R are true and R is the correct explanation of A.
b) Both A and R are true but R is not the correct explanation of A.
c) A is true but R is false.
d) A is false but R is true.

3. The effect of adding feedback makes the system__________
a) Linear
b) Non-linear
c) Time variant
d) Time invariant

4. Regenerative feedback is also called as_________________
a) Negative feedback

d) None of the mentioned

6. Which of the following are true:
a) Sensitivity of regenerative feedback is more than negative feedback but less than non-feedback system
b) Sensitivity of regenerative feedback is more non-feedback system but less than negative feedback system
c) Sensitivity of regenerative feedback is less than both
d) Sensitivity of regenerative feedback is more than both

7. Which of the following are the characteristics of regenerative feedback:
a) Zero damping
b) Stable
