Can I use the Fourier Transform to analyze the Sun's Spectrum?

[Hugom42]

I'm learning digital signal processing in my engineer class, but I'm more interested in apply these things into Astrophysics, so i know a little bit about for what is useful the Fourier Transform, so i thought why not use this in Analyzing the sun spectra! But what do you think!? Is it useful!? What do i need !?

What are you trying to learn from this? Remember, the spectrum is already in the frequency domain.

Sun's spectrum is Fourier transform of solar radiation.

Look up FTIR, then consider why it won't work in visible and UV.
