Introduction to Digital Systems

A system is a set of related components that work as a whole to achieve a goal. A system contains inputs, behavior and outputs.

Behavior is a function that translates inputs to output.

Components are electronics blocks – digital, analog, or mixed signal. Digital System is a system in which signals have a finite number of discrete values. Analog System has values from a continuous set and Mixed Signal System has both Digital and Analog parts.

Generally, signals are represented by two methods, i.e., Digital and Analog System. Digital Signal is limited to only a few possible values, generally represented by Binary logic 0 (0 – 0.8 volts) and logic 1 (2.0 – 5.0 volts). Whereas Analog Signal varies continuously.
