Physics - Semiconductors Question with Solution | TestHub

From the given truth table, the output $Y$ is $0$ only when both inputs $A$ and $B$ are $1$. For all other combinations of inputs, the output $Y$ is $1$.

This is the exact complement of an AND gate, where the output is $1$ only when both inputs are $1$.

The Boolean expression for this truth table is $Y=\overline{A\cdot B}$, which corresponds to a NAND gate.

Answer: NAND gate
