WEBApr 13, 2024 · The Fourier transform is a generalization of the complex Fourier series in the limit as L->infty. Replace the discrete A_n with the continuous F(k)dk while letting n/L->k. Then change the sum to an integral, and the equations become f(x) = int_(-infty)^inftyF(k)e^(2piikx)dk (1) F(k) = int_(-infty)^inftyf(x)e^(-2piikx)dx.

WEBWhat does the Fourier Transform do? Given a smoothie, it finds the recipe. How? Run the smoothie through filters to extract each ingredient. Why? Recipes are easier to analyze, compare, and modify than the smoothie itself. How do we get the smoothie back? Blend the ingredients. Here's the "math English" version of the above:
