I only just now discovered Wiener's work "Generalized Harmonic Analysis", which from what I understand was a generalization of Fourier Transform for functions that are not square-integrable.
However, we now know that we can take the generalized fourier transform of bounded signals to get distributions (generalized functions).
Wiener published his work in 1930, while according to Wikipedia Schwartz only introduced distribution theory in the late 1940s, so Wiener most likely didn't use them in his work. Is this correct?
And if so, is Wiener's work now obsolete because of generalized functions?
