Fourier analysis

In mathematics, the sciences, and engineering, Fourier analysis () is the study of the way general functions on the real line, circle, integers, finite cyclic group or general locally compact Abelian group may be represented or approximated by sums of trigonometric functions or more conveniently, complex exponentials. Fourier analysis grew from...
