Homework Help: Computing Fourier transforms with exponentials

  1. Mar 26, 2012 #1
    1. The problem statement, all variables and given/known data

    Compute the Fourier transform of f(x)=exp(-b|x|), b>0

    2. Relevant equations


    3. The attempt at a solution


    How do I solve this? I've tried to solve it but can't get to a solution because of the modulus sign.
