Mathematical Preliminaries for Transforms, Subbands, and Wavelets

Abstract

In this chapter, we will review some of the mathematical background necessary for the study of transforms, subbands, and wavelets. The topics include Fourier series, Fourier transforms, and their discrete counterparts. We will also look at sampling and briefly review some linear system concepts.

12.1 Overview

The first step in the design of any data compression scheme is modeling the source process. Developing a good model for a process or signal requires comprehension and understanding of the process. And in ...
