In how many ways one can design NOT gate? Describe them briefly.

Question

Anand · Accepted Answer

NOT gate can be built in many ways. It is not necessary to that both the inputs of NAND/NOR should be same. We can also design the NOT gate with the help of 2X1 MUX.

To prove that there are many ways we can also state that the NOT gate can be built with DECODER.

Mithun Mahadevan · Answer

The NOT can be designed using NAND and NOR gate,these two gates are also known as the universal gates. Using NAND gate, it can take two same 2 i/p's  for implementation of NOT gate. The NAND gate can produce 1,when both i/p's are 0. It can produce the 0 ,when both i/p's are 1.Using NOR gate ,it can take same 2 i/p's  .produce 1 when both i/p's are  0 and produce 0 when both i/p's are 1.
