Getting the components of a sum of square waves

    If I have a periodic function that is say a sum of a number of sine functions I can use a Fourier Transform to get the component functions.

    Now, if I have a bunch of square waves of differing amplitudes and frequencies that I add up into a resultant waveform. Given that waveform what'd be the mathematical operation to get at its individual component square waves? Is there any?

    Surely you just mean the 'inverse Fourier transform'?

    I think not; but now I'm confused. I'll read / think more and get back. Thanks!
