Abstract
The primary new component of discrete (or digital, we won’t treat the effects of quantization) systems is the notion of time discretization. No longer are we dealing with variables which are functions of time, now we have sequences of discrete numbers. These discrete numbers may come from sampling a continuous variable, or they may be generated within a computer. In either case, the tools that were used in the analysis of continuous variables will no longer work. We need new methods.
