Editing Logic Gates

Use this as reference for some of the basic gates: [http://en.wikipedia.org/wiki/Logic_gate#Symbols Logic Gate Symbols]

==AND==

This only outputs high when all inputs are high.

==OR==

This outputs high when any of the inputs are high.

==XOR==

This outputs high only if ALL of the inputs are different (for binary applications, only 2-inputs are possible).

==NOT==

This inverts the input.  If input is high, output is low, and vice-versa.

By applying this logic to the previous gates, we can come up with a few more:

==NAND==

This outputs the opposite of an AND gate, which means that the output is high if the inputs are anything but all on.

==NOR==

This is the opposite the OR gate, which means the output is high only if all inputs are low.

==XNOR==

This is the opposite of the XOR gate, which means the output is high only if all inputs are the same.
