Fourier transform

  1. Jul 12, 2005 #1
    Dear Ones,

    I have a really big problem with the Fourier Transform, and looking for anybody who can help me to solve this problem.

    The question is:

    I performed the FT twice. Normally the second FT = f(-x) (if the original function was f(x)), however I repetead the FT on the first, positive, power spectrum. The result is something like an finite impulse train, but the height of the spikes is not equal and the location of the highest spike is changes according to the original spectrum.

    Is there somebody who can explain what is the rule of the location of the highest peak?
