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. These operations are what make all ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

This door handle with a key-code lock does it all with 3D printing ... set or unset bits, logic gates, propagation issues, the whole works. But there are added challenges in this system, like ...

An AND gate usually has two inputs. AND tells us that both Input A AND Input B have to be 1 (or ON) in order for the output to be 1. Otherwise the output is 0.

A single digital signal has only two states - on or off. However, if you use two inputs you can double the number of possible states, to four.
