Logic Gates: Types, Properties, and Implementation

Definition and Basic Concept Logic gates are electronic circuits that produce outputs based on given inputs according to specific logical relationships. Each gate implements a particular logical function, and the output depends on the combination of input values. Logic gates are fundamental...

What is a universal gate in digital logic?

A universal gate is a logic gate from which all other logic gates can be constructed. NAND and NOR gates are universal gates, meaning any Boolean function can be implemented using only NAND or only NOR gates.

Explain De Morgan's laws in Boolean algebra.

$\overline{A + B} = \overline{A} \cdot \overline{B}$ and $\overline{A \cdot B} = \overline{A} + \overline{B}$ — these laws show how to distribute negation over AND and OR operations, allowing simplification and transformation of logic expressions.
