Signals & SystemsLaplace Transform

For x(t)=e^(-2t)u(t), the ROC of its bilateral Laplace transform is?

  • ARe{s}>-2
  • BRe{s}<-2
  • CRe{s}=0 only
  • DAll s including the pole
Report an error
Correct Answer: A. Re{s}>-2
Explanation: A right-sided exponential has ROC to the right of its pole at s=-2.
Reference: Standard signals and systems: laplace transform
