Using Boolean algebra as switching algebra, complex circuits are expressed so that they can be evaluated mathematically.

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output.

Each gate is actually a circuit, typically consisting of transistors and biasing resistors. As an example, the transistor-transistor logic (TTL) 7408 chip contains four, two-input AND gates in one ...

Boolean algebra, and other forms of abstract propositional logic, are based on dealing with compound propositions made up of simple propositions joined by logical connectors like "and", "or", and ...
