Describe this FFT

  1. Jul 26, 2004 #1
    Could somone possibly describe this this FFT. I need to know the properties and frequency. Thanks for anyone's time who helps.

    (BTW, if this is in the wrong forum, I could use some redirection).

    That's a fast fourier transform?

    I don't see any axes... what are we looking at? :confused:

    Psst... it's a 2D FFT. (I don't know what it means though.)
