AND gate MCQs with Answers

AND gate MCQs

The logic gate with two inputs and one output is called as AND gate. AND operation means the multiplication of inputs. i.e. the output will be high if and only if both the input signal high, in rest all conditions the output of AND operation is low.

The Boolean expression for the AND operation is given as

Y = AB

Where A and B represents input and Y represents the output.

The input-output table for AND operation is given then written as,

Input A

Input B Output Y=AB
1 1
