Question

Identify the true statement for $OR$ gate

• A. Output Y will be 1 when input A or B or both are 1
• B. Output Y will be 0 when the either of the inputs A or B is 1
• C. Output Y will be 1 only when both the inputs A and Bare 1
• D. Output Y will be 1 only when either of the inputs A and B are 1

Answer 1

Answer: (A)

In an $OR$ gate, output $V$ is $1$ only when either or both the inputs $A$ and $B$ are $1$. The truth table is shown below.

$A$	$B$	$Y$
$0$	$0$	$0$
$0$	$1$	$1$
$1$	$0$	$1$
$1$	$1$	$1$
