The given truth table is for which logic gate A B Y 1 1 0 0 1 1 1 0 1 0 0 1 (a) NAND (b) XOR (c) NOR (d) OR

Answer: (a). Read the table: Y = 0 only for A = 1, B = 1; for every other input Y = 1. This is the complement of AND: Y = A · B. So the answer is (a) NAND.

Logic Gates

The given truth table is for which logic gate

$A \quad B \quad Y$

$1 \quad 1 \quad 0$

$0 \quad 1 \quad 1$

$1 \quad 0 \quad 1$

$0 \quad 0 \quad 1$

Show answer and solution

Answer: (a)

Read the table: $Y = 0$ only for $A = 1, B = 1$ ; for every other input $Y = 1$ .
This is the complement of AND: $Y = \overline{A \cdot B}$ .
So the answer is (a) NAND.
