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 ...
