A Digital system is an interconnection of digital modules and it is a system that manipulates
discrete elements of information that is represented internally in the binary form.
Now a day’s digital systems are used in wide variety of industrial and consumer products such as
automated industrial machinery, pocket calculators, microprocessors, digital computers, digital watches,
TV games and signal processing and so on.
Characteristics of Digital systems
Digital systems manipulate discrete elements of information.
Discrete elements are nothing but the digits such as 10 decimal digits or 26 letters of alphabetsand
so on.
Digital systems use physical quantities called signals to represent discrete elements.
In digital systems, the signals have two discrete values and are therefore said to be binary.
A signal in digital system represents one binary digit called a bit. The bit has a value either 0 or 1.
