Experiment 4 - The NOT Operation (Inversion)

The NOT operation, also known as inversion, complement or negation, inverts the variable A.

You can picture the behavior of a NOT operation by a switch that opens when pressed. Thus, the result Q produces the truth table...

In logic equations the operator \(\neg\) or a horizontal line is used for the NOT operation... $$Q = \neg A \equiv \overline{A}$$ (Speaking: not A).

With the C-MOS IC 4069, you build an NOT operation...
