Today in my circuits class, we were talking about Fourier transforms and my professor briefly said something about how a Fourier transform is a rotation in infinite dimensional space. I would ask him more about it but since it's beyond our course I'd rather not bug him. Where can I learn more about this concept? Or what exactly is going on with that idea?(adsbygoogle = window.adsbygoogle || []).push({});
