Abstract
In this chapter we will investigate the fundamental topic of discrete-time signals and systems. We first introduce some basic and useful discrete-time signals, like the unit impulse, the sinusoidal and white Gaussian random sequences. Then we define and represent discrete-time systems. We give some criteria with which these systems can be classified. Then for the important class of linear time-invariant (LTI) systems we focus on the state-space description that will form the basis for the analysis on following ...
