# Definition:Logical NOR/Truth Table

The characteristic truth table of the logical NOR operator $p \downarrow q$ is as follows:
$\begin{array}{|cc||c|} \hline p & q & p \downarrow q \\ \hline F & F & T \\ F & T & F \\ T & F & F \\ T & T & F \\ \hline \end{array}$
$\begin{array}{c|cc} \downarrow & T & F \\ \hline T & F & F \\ F & F & T \\ \end{array}$
