Assertion (A): Location of the poles of a transfer function in the s-plane affects greatly the transient response of the system and hence stability.
Reason (R): The poles that are close to the imaginary axis in the left-half s-plane give rise to transient responses that will decay relatively slowly, whereas the poles that are far away from the axis (relative to the dominant poles) correspond to fast-decaying time responses. 
  • a)
    Both A and R are true and R is a correct explanation of A,
  • b)
    Both A and R are true but R is not a correct explanation of A.
  • c)
    A is true but R is false.
  • d)
    A is false but R is true.
Correct answer is option 'A'. Can you explain this answer?

Understanding the Assertion and Reason
The assertion (A) and reason (R) provided relate to the impact of pole locations in the s-plane on system behavior, particularly in terms of transient response and stability.
Assertion (A) Explained
- The location of poles in the s-plane is crucial for determining system stability.
- Poles in the left-half plane indicate a st

Understanding System Response to Unbounded Input
In control systems and signal processing, the behavior of a system under different conditions is crucial for analysis. When a system is subjected to unbounded input, it raises important questions regarding its classification.
Unbounded Input Explained
- An unbounded input refers to an input signal that grows indefinitely
