create circuits and logic gates

, as well as to check computer chips. Knowledge of digital logic lends itself to many different computer technology design and engineering professions.

What is logic in digital logic design?

A Digital Logic Gate is

an electronic circuit which makes logical decisions based on the combination of present on its inputs

. Digital logic gates can have more than one input, for example, inputs A, B, C, D etc., but generally only have one digital output, (Q).

What are the applications of logic gates?

Logic gates are used

in microcontrollers, microprocessors, electronic and electrical project circuits, and embedded system applications

. The basic logic gates are categorized into seven types as AND, OR, XOR, NAND, NOR, XNOR, and NOT. These are the important digital devices, mainly based on the Boolean function.
