What are the logic gates three basic functions
- AND
- OR
- NOT
What functions can be made by combining the three basic logic functions
- NAND
- NOR
- EXCLUSIVE OR
- EXCLUSIVE NOR

What is the output of a NOT gate
An inverter has only one input, and the output is always the opposite of the input
When does an AND gate produce a logic 1?
When all inputs are at logic 1
When does a NAND gate produce logic 1?
The output logic is 1 when any output is 0
When does a NAND gate produce logic 0?
The output is a logic 0 only when all inputs are 1
When does a OR gate produce logic 1?
If any of the logic inputs are logic 1
When does a NOR gate produce logic 1?
The output logic is only logic 1 if all input logics are at logic 1
When does a XNOR gate produce logic 1?
The output is at logic 1 when both inputs are at logic 0 or both inputs are at logic 1
Which truth table?
NOT gate (inverter)
