Chapter 8. Discrete-Time Signals and Systems
It's like dèjá-vu, all over again.
Lawrence “Yogi” Berra (1925) Yankees baseball player

8.1. Introduction

As you will see in this chapter, the basic theory of discrete-time signals and systems is very much like that for continuous-time signals and systems. However, there are significant differences that need to be understood. Specifically in this chapter we will consider the following contrasting issues:
■ Discrete-time signals resulting from sampling of continuous-time signals are only available at uniform times determined by the sampling period; they are not defined in-between sampling periods. It is important to emphasize the significance of sampling according to the Nyquist sampling rate condition since ...
