    hi..i wnt to know how the frequency-domain graph(FFT) is analyzed/studied? wht those high amplitude lines in the middle with lower amplitude lines following them to both the sides mean?
    Wht does having low frequnecies in a signal mean? is it gud or a bad one?

    Any help to clear my basic concepts wud b appreciated.
    Thnx.
