Explanation:

supporting img

$Y = \overset{―}{\bar{A} \cdot \bar{B}} = \overset{―}{\bar{A}} + \overset{―}{\bar{B}} = A + B$
Thus, this combination is OR gate.

365209 For the given digital circuit, write the truth table and identify the logic gate it represents
supporting img

1 NAND gate

2 OR gate

3 AND gate

4 NOR gate

Explanation:

The output $Y$ of the circuit is
$Y = \overset{―}{\overset{―}{A} + \overset{―}{B}} = \overset{―}{\overset{―}{A}} . \overset{―}{\overset{―}{B}} = A . B$
It is Boolean expression for AND gate
Hence the given digital circuit represents the AND gate.

1, 1, 0

3

0, 1, 0

4

1, 0, 0

Explanation:

For $Y$ to be 1, both $C$ and $D$ should be 1. For $D$ to be 1, at least one of its inputs ( $A$ or $B$ ) should be 1.
Hence option (1), where $A = 1, B = 0$ and $C = 1$ , is correct.
