English

Noun

NOT (plural NOTs)

1. (mathematics, logic) A unary operation on logical values that changes true to false, and false to true.
   • 2022 August 4, William Bahn, “Boolean Algebra Laws—Delving Into Boolean Identities”, in All About Circuits‎^[1]:

     Notice that the NOT symbol is simply a BUF symbol followed by a bubble. The bubble represents logical inversion and is the actual NOT gate. Anytime you see a bubble attached to a gate pin, you can detach it from the pin and insert a separate NOT gate in its place without affecting the resulting logic.

Usage notes

• The symbols ¬, !, ~, ˈ and overbar (as in Ā for "not A") have all been used for the NOT operator in various contexts.
• Boolean variables and states (AND, OR, NOT, TRUE, FALSE etc.) are commonly written in all uppercase in order to distinguish them from the ordinary uses of the words.
