Homework Help: Magnitude in frequency domain of Fourier Transform

  1. Nov 16, 2012 #1
    1. The problem statement, all variables and given/known data
    Hi All, I'm just trying to practice graphing signals in frequency domain and I came across a stiuation I wasn't familiar with. If the exp() has a constant*t in it I'm not sure how to graph it, I remember that just cos it like a double sided exp(jwt) but with half the magnitude. I've attached a drawing to better illustrate the question of how to graph X(w),
    I've worked out that X(w) = 1/2[1/(3+j(w-10)) + 1/(3+j(w+10))] from x(t) but not sure what that magnitude in frequency domain looks like.

    2. Relevant equations

    Please see picture for oringinal x(t)

    3. The attempt at a solution

    I thought I might have posted this question before in the wrong area (because I got no reply) Thanks heaps!
