Physics - Semiconductors Question with Solution | TestHub

A NAND gate is a combination of an AND gate followed by a NOT gate.

The Boolean expression for an AND gate with inputs $A$ and $B$ is $Y^{\prime }=A\cdot B$.

Passing this output through a NOT gate gives the final output $Y=\overline{Y^{\prime }}$.

Therefore, the Boolean expression for a NAND gate is $Y=\overline{A\cdot B}$.

Answer: $Y=\overline{A\cdot B}$
