A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic circuits directly, a much more versatile solution was to ...

Each operator has a standard symbol that can be used when drawing logic gate circuits. In an AND gate, both inputs need to be 1 for the output to be 1.
