Identify an unbounded input from inputs whose transfer functions are given below______________?
Correct answer: C. 1/S2
- A. 1
- B. 1/S
- C. 1/S2
- D. 1/(S2 + 1)
Explanation
The transform 1/s² represents a ramp input, whose magnitude increases indefinitely with time, making it unbounded. A step and a sinusoid represented by 1/(s²+1) remain bounded in amplitude.
