Logic Gates - Technical MCQs

Q1:

What input values will cause an AND logic gate to produce a HIGH output?

A At least one input is HIGH.

B At least one input is LOW.

C All inputs are HIGH.

D All inputs are LOW.

ANS:C - All inputs are HIGH.

By Truth table we can say that Output of AND gate will be high when both the inputs are high.

1 1 = 1
1 0 = 0
0 1 = 0
0 0 = 0
