Signals & SystemsLTI Frequency Response

If an LTI system is excited by e^(j omega t), the response is the same exponential multiplied by?

  • AH(j omega)
  • BSampling period only
  • CZero always
  • Domega squared always
Report an error
Correct Answer: A. H(j omega)
Explanation: Complex exponentials are eigenfunctions of LTI systems; output is H(jomega)e^(jomega t).
Reference: Standard signals and systems: lti frequency response
