The OR gate is said to be a binary adder circuit at which if any one of the input is said to be high - 1, then the output is high, input number varies depending upon the circuit.

AS We know the OR gate is the Addition and it gives high output only when any one of the inputs is high.

A B Y=A+B
0 0 0 LOW
0 1 1 HIGH
1 0 1 HIGH
1 1 1 HIGH
(1)

Since OR gate is addition hence any high i/p will result in high o/p, so all i/p should be low for low o/p.

Any input is high means the output will be high.

OR TRUTH TABLE

i/p1 i/p2 o/p
0 0 0
0 1 1
1 0 1
1 1 1
all i/p are low at first case and o/p is also low

because OR gate is a addition operation
