Consider the following Laplace transforms of certain signals. For which of the following. final value theorem is not applicable?
Right Answer is:
(S + 1)/(S – 2)
The final value theorem applies only if all the poles of X(s) are in the left half of the s-plane, with almost a single pole at s = 0.
From the given above option (S + 1)/(S – 2) is unstable as its poles lie on the right half of the s-plane therefore the final value theorem can not be applied.
