Because AND gate 3 outputs are zero in 3cases these 3 cases the input is one or more inputs are zero so checking the AND gate truth table answer is and gate.

AND gate operation is multiplication so any one of the input '0' the total o/p also '0'.

Ex:

A B C Y
0 1 1 0
1 1 0 0
1 0 1 0
1 0 1 0

Then what is meant by OR same logic is applied i.e (when both input is zero the output will be zero). Can you please explain me?

Akshaya said:   9 years ago
A B O/p
0 0 0
0 1 0
1 0 0
1 1 1

When one or two I/p is zero, the output will be low for AND gate.

Why can't OR gate be the answer? Because when one or more inputs is 0 the answer would be low state.

A B Y = A * B

0 0 0
0 1 0
1 0 0
1 1 1

Because AND gate ttree output arr zero and only one output is high.
