But do we have more than 2 input NOR gate?

Just add all three inputs and NOT it for the actual o/p.

i/p- 000 then o/p- 111 (high).

Yeah, right thanks @Punju.

Punju said:   9 years ago
By the truth table at 0 0 input output is 1 and remaining all are 0. Therefore the high output is the 1.

Therefore, the ans is option : A.

If all input is 1 then it is high, if all inputs are zero then it is low.

Above all are false.

NOR gate consider the outputs to be high if the inversion of it is high.

Yes @Nandi 4078b is the single 8 inputs norgate in CMOS technology.

But it is a 3 input nor gate not 2 input.
