Fourier Transform Decomposition

  1. Aug 25, 2009 #1
    If i've a real signal, and I do a forward Fourier transformation
    I receive two parts:
    Real and Imaginary,
    what's the difference between them?

    i need to represent the transform in a software program,
    which part do i represent ?
