    I was trying to do some EMI analysis on Comon mode chokes & inductors.
    i got their transient response from which i also got their FFT. The
    problem wat i am facing now is how do i interpret the results, how to
    identify the fundamental harmonics & the distortion occuring & also
    wat exactly does this fourier transform represent. I wanted to analyse
    only the EMI FILters(cmc & inductors) whereas the circuit contains
    other components like drivers etc, so how to confine only to the emi
    filter .

    is it white noise or electromagnetic interferance your trying to
    effectively suppress in this application.

    EMI performance depends as much on component suitability and tracking
    layout as Spice simulations.

    Sounds to me like you need to learn the basics. Apologies if I've misread
    you.
