Fourier series - Wikipedia, the free encyclopedia In mathematics, a Fourier series (English pronunciation: /ˈfɔərieɪ/) is a way to represent a wave-like function as the sum of simple sine waves. More formally, it decomposes any periodic function or periodic signal into the sum of a (possibly infinite) se
