Abstract
The past few years have seen significant advances in computer technology and its incorporation into engineering and other applications. In these applications, the various signals acting in and on systems occur as data sequences occurring at discrete time instants. Some familiar examples of systems controlled by discrete data sequences are:
-
1.
National Economies
-
2.
Radar-tracking systems
-
3.
Data-transmission links
We note that in such systems the information is available only in samples. In this chapter we present methods for the analysis of systems incorporating digital devices, which are called discrete-time systems. As used here, the term discrete system refers to any system whose operation or output is conveniently described on a discrete time scale even though the system characteristics may in general be given in continuous time.
