Which logic gate is equivalent to these combinations of logic gatesa)N...
CONCEPT:
Logic gates are small electronic circuits that are used to control the output current according to our requirements.
These are the following symbols to represent logic gates

These are the Properties of logic gates:
And gate(.) – It gives us an output one only when both the inputs as 1 otherwise 0
OR gate(+) – The OR gate gives an output of 1 if either of the two inputs is 1, it gives 0 otherwise.
NOT gate(‘) – The NOT gate gives an output of 1 input is 0 and vice-versa.
NOR gate – The combination of NOT and OR gates, so it will have its output reversed.
NAND gate – The combination of NOT and AND gates, so it will have its output reversed.
In our logic circuit, we used NOT and NOR in such a way that current from both A and B will pass through NOT gates and then send to the NOR gate hence the Truth table of the following circuit will be:

This means the output will be always 1 when both inputs are 1, just like the AND gate.
