Digital electronics is based on a number of discrete voltage levels, usually two. Analog electronics, on the other hand, uses continuous voltages levels to represent variables directly. Digital circuits most commonly represent Boolean algebra and are the basis of all digital computers.

Digital electronics, as a subject, has remained as a core subject in Computers, Electronics and Electrical branches of engineering. With the coming of Hardware Descriptive Languages, its currency is unquestionable.

The content-organization of the book, Digital Principles and Applications, 6th Edition, reflects the way digital electronics is taught today. The book starts from the basics of digital systems and goes on to explore the more advanced components of digital systems.
