Q. A logic gate and its truth table are shown below

[table] $\mathbf{A}$ | $\mathbf{B}$ | $\mathbf{Y}$ ; $0$ $0$ $1$ $1$ | $0$ $1$ $0$ $1$ | $0$ $1$ $1$ $1$ [/table] The gate is

A) NOR
B) AND
C) OR
D) NOT
Explanation

(c) The given truth table express the Boolean expression as
$Y = A + B$
Since, 0 = 0 + 0
1= 0 + 1
$1 = 1 + 0$
$1 = 1 + 1$
This the Boolean expression of OR gate.
