[_] captivating Anon 3430871 interesting
>> [_] Anon 3430904 I wish I was smart enough to understand the math behind this but holy shit calculus so very dry and I'm so very dumb
>> [_] Anon 3430907 >># Electrical engineering anon here. Fourier transforms and similar transforms are our bread and butter, especially if you do digital signal processing. However, even I don't know as much about them as I'd like. To really understand them, you need to study analysis from a pure math perspective. It's really cool stuff and not too dry once you start imagining and working with the concepts.
>> [_] Anon 3430910 >># They introduced us to transforms in the last class I took but I bombed calc so very little of it made any sense to me. I think I get the absolute basics of it but if you asked me to explain it there's fuck all I could put in to words.
>> [_] Anon 3430914 >># tl;dr version - you can represent any signal as an infinite sum of perfect sine waves (the flash shows how, for example, as you add more and more sine waves of a certain form, you can get closer and closer to a square wave). A fourier transform works on this principle to decompose an arbitrary signal into a spectrum of frequencies and amplitudes (for example, if you do a transform on the noise in a current measured by a probe in a plasma, you'll see peaks at the frequencies of different plasma waves, which you can use to determine physical properties).
