Signals & SystemsConvolution

If x(t)=e^(-t)u(t) and h(t)=delta(t), the output is?

  • Ae^(-t)u(t)
  • Bdelta(t)
  • Cu(t)
  • De^t u(t)
Report an error
Correct Answer: A. e^(-t)u(t)
Explanation: Convolution with delta leaves the signal unchanged.
Reference: Standard signals and systems: convolution
