CDMA Method: by Alan Wong

The document describes an EX-NOR gate, which is an EX-OR gate with an inverted output. An EX-NOR gate outputs a 1 only when its two inputs are the same value (both 0 or both 1), otherwise it outputs a 0. It has two inputs and one output, as represented by its traditional and IEC symbols and demonstrated in its truth table.

CDMA method

By Alan Wong
EX-NOR (EXclusive-NOR) gate
This is an EX-OR gate with the output inverted, as shown by the 'o' on the output.
The output Q is true if inputs A and B are the SAME (both true or both
false): Q = (A AND B) OR (NOT A AND NOT B)

EX-NOR gates can only have 2 inputs.


Input A Input B Output Q

0 0 1

0 1 0

1 0 0
