Laplace limits

  1. Aug 3, 2004 #1
    How would you go about finding the limits of the general laplace transform function for periodic functions?

    Could u clarify the question?
    More specifically what are these *limits* that u talk abt?

    If the laplace transform of f for a periodic function is given by

    L(f)(s)=

    1/(1-e^{-sT})) *integral from 0 to T of (e^{-st}f(t)dt))


    then how do you find
    lim_{sā†’āˆž}L(f)(s) and lim_{sā†’0}L(f)(s).

    You need to know what the integral of e-stf(t) looks like before you can do that. First integrate to get your function of s, then handle it on a case by case basis.
