What function does NAND perform with a single input P?

Choose one option.

Show answer

Explanation

With a single input, \(P\land P\equiv P\), so NAND produces \(\neg P\).

Given propositions \(P\) and \(Q\), the NAND operation is the negation of their conjunction.

\[P\mathbin{\uparrow}Q=\neg(P\land Q)\]
