Nor is a gate term used to describe logic components. \\ NOR gate (NOR = Not OR) \\ This is an OR gate with the output inverted, as shown by the 'o' on the output. \\ The output Q is true if NOT inputs A OR B are true: Q = NOT (A OR B) \\ A NOR gate can have two or more inputs, its output is true if no inputs are true. | Nor is a gate term used to describe logic components. \\ NOR gate (NOR = Not OR) \\ This is an OR gate with the output inverted, as shown by the 'o' on the output. \\ The output Q is true if NOT inputs A OR B are true: Q = NOT (A OR B) \\ A NOR gate can have two or more inputs, its output is true if no inputs are true. |
