Question

Describe : (i) NAND gate, and (ii) NOR gate.

Answer 1

NAND gate -this is an ANDGate followed by a not gate .in inputs A and B are both one (1) the output You is not 1.the gates gets its name from NOT AND behaviour.NAND gate are also called as universal Gates since by using these Gates your can also realise other basic Gates like OR,AND and NOT.

NOR gate -it has two or more inputs and one output .A Not operation applied after OR gate gives a NOT-OR gate (or simply NOR gate).its output Y is 1 only when both input A and B are zero that is;neither one input or the other is 1

there can be two inputs or more in a NOR Gate but has only one output .

Boolean expression for this great

Y=A+B

So mate this is your answer.

I hope it helps you.

please mark as brain list.
