The below truth table corresponds to
A B Y 0 0 1 1 0 1 0 1 1 1 1 0
| A | B | Y |
|---|---|---|
| 0 | 0 | 1 |
| 1 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 1 | 0 |
- Correct answerANAND gate
- BXOR gate
- COR gate
- DNOR gate
Solution
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
