The faces of Convolution: from the Fourier theory to algebraic signal processing

Signal Processing 2023-07-18 v1

Abstract

In this expository article, we provide a self-contained overview of the notion of convolution embedded in different theories: from the classical Fourier theory to the theory of algebraic signal processing. We discuss their relations and differences. Toward the end, we provide an opinion on whether there is a consistent approach to convolution that unifies seemingly different approaches by different theories.
