| 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. |

| | =====NV===== |
| | __N__ode __V__ariable a [[glossary:glossary_c#cbus|CBUS]] term referring to a value which controls the overall behaviour of a node. For example in the CANACE8C module, taking an input low generates an On event, when that input returns high this normally generates an Off event. This behaviour can be modified by one of the NVs where a set(1) bit within the NV will cause the associated Off event generation to be suppressed. |
