Chapter 2

Discrete Time Systems Theory

Chapter Outline

As explained in the previous chapter, automotive electronic control and instrumentation systems (as well as virtually all other electrical systems) are implemented with digital electronics as at least some component or subsystem. Digital controllers and/or signal processing subsystems incorporate one or more microprocessors or microcontrollers, each having a stored program to run the system. Such systems are fundamentally discrete time systems.

However, automotive electronic systems also incorporate analog or continuous time components (e.g., sensors ...
