Energy-density spectrum: double entry in wiki
This subject is already included in the wikipage on spectral density. The same holds for Parseval's theorem. This page should thus be updated to account for this. I created the link from the Spectral density page to this page here and made also a comment there.Sigmout (talk) 09:06, 18 August 2008 (UTC)

Any relationship to Lebesgue spaces and functional analysis?
I am only still starting to study signal processing, but I am curious if the definition of energy here has any relationship to, or underpinnings from, the theory around Lp spaces (aka Lebesgue spaces) or functional analysis in general?

If so, it might be nice to make this connection in the article?

I might be out of my depth here, so I'd be very glad to hear input from anyone who's more familiar with these subjects.

Thanks!
