Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them. Using relays is one of them, and you can literally see how they work.

For those just getting their start in digital logic, this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic ...

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.

When pulsed at their inputs, they change their state. To learn how gates work in a circuit, see Boolean logic. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Box 1: Criteria for practical optical logic. The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few ...

Last week, MIT researchers published a blog post highlighting a paper detailing work on fully 3D printable electronics — ...
