Question

explain the NOR gates as universal gate​

Answer 1

Answer

NOR gate is a logical circuit, that will produce 1 output only when both inputs are 0. If any input is 1, then output will be 0. NOR gate can have two or more inputs and one output. NOR gate is inversion of OR gate.

i.e. OR gate followed by NOT gate.
