digital logic symbols

gates

AND gate

A basic digital logic gate that outputs 1 only if all its inputs are 1. Can have more than two inputs.

OR gate

A basic digital logic gate that outputs 1 if at least one of its inputs is 1. Can have more than two inputs

Not gate

A basic digital logic circuit that inverses the input 1 to 0, 0 to 1.

NOR gate

A basic digital logic gate that produces a 1 only if all inputs are 0. NOT OR. Can have more than two inputs.

NAND

A basic digital logic gate that produces a 1 as long as the inputs are not all 1. only produces 0 when all inputs are 1. Can have more than two inputs.

XOR gate

A basic digital logic gate that only produces a 1 when its inputs are different. Can add more than two inputs will only be 1 only when exactly 1 of its inputs is 1.

XNOR gate

A basic digital logic gate that produces a 1 only when its inputs are the same. (the inverse of a XOR gate). CAN ONLY HAVE TWO INPUTS.
