How do you design a half-adder using NOR gate?

Answer 1

Use 4 NOR gates.

For the 1st NOR gate, inputs should be x' and y

For the 2nd NOR gate,inputs should be y' and x

The outputs of NOR 1 and NOR 2 are taken as inputs of NOR gate 3

The output of NOR 3 is the complemented form of the output required, so, just complement the output of NOR gate 3 with another NOR gate and Viola!, you have your HALF ADDER OUTPUT

PS:I have used a double rail logic, where both x:x' and y:y' are available

Answer 2

an 2 input AND gate can be realize using 3 NOR gates.

Let ,A and B are the input and x be the output.

x=A.B= NOR(NOR(A) NOR(B))

Answer 3

If you tie the two inputs on a NOR gate together and use that as a single input, you will create a simple NOT gate.

Answer 4

Short the two inputs of the NAND gate, so that only one input is needed. Now apply the desired input ie '0' or '1'. The output will be of a NOT gate.

Answer 5

tie one input of the XOR gate high.
