can anyone give me a simple explanation what fourier analysis is all about? i have read wiki and it is a little confusing(adsbygoogle = window.adsbygoogle || []).push({});

what am i doing when i express a funciton as a series? what is the difference to a transform?

i know how to follow the steps of a fourier series/transform, but i have no idea why i am doing it?

thanks!
