12.1 Introduction
In this chapter we will present applications of the theory of discrete-time signals and systems to three important areas: digital signal processing, digital control, and digital communications. The material in this chapter is meant to be a more motivational than detailed presentation. We encourage our readers to look for the details in excellent textbooks in these three areas [54, 22, 16].
Given the advances in digital technologies and computers, processing of signals is being done mostly digitally. Early results in sampling, analog-to-digital conversion, ...
