Understanding Fourier Analysis on Finite Groups

Fourier analysis on finite groups is an extension of the classical Fourier analysis, which deals with functions on the real line or in Euclidean space. In the finite group setting, the main idea is to represent functions on a finite group as linear combinations of characters, which are mathematical objects that provide information about the symmetry of the group.
