Question

establish the action of NOR gate as universal gate​

Answer 1

One NOR input pin is connected to the input signal A while all other input pins are connected to logic 0. The output will be A'. Thus, the NOR gate is a universal gate since it can implement the AND, OR and NOT functions

Answer 2

Answer:

We have seen how the NAND gate can be used to make all the three basic gates by using that alone. Now we will discuss the same in case of NOR gate.

Explanation:

The above diagram is of an OR gate made by only using NOR gates. The output of this gate is exactly similar to that of a single OR gate. We can see the circuit arrangement of OR gate using, NOR gate is similar to that of AND gate using NAND gates.
