A transfer function has poles at s=-2 and s=-5. Which pole is dominant in the usual time-response sense?

  • As=-5
  • Bs=-2
  • CBoth are always equally dominant
  • DNeither pole affects response
Report an error
Correct Answer: B. s=-2
Explanation: The pole closer to the imaginary axis, s=-2, corresponds to the slower decaying exponential and generally dominates the long-term transient.
