The given electrical network is equivalent to : 1. OR gate 2. NOR gate 3. NOT gate 4. AND gate

Answer: 2. NOR gate Key idea: trace the logic step by step. First gate is a NOR: output A+B . Second gate is a NOR with both inputs joined, which acts as a NOT: output A+B . Last gate is a NOT: output Y=A+B . This is the NOR gate.

Answer: 2. NOR gate

Key idea: trace the logic step by step.

First gate is a NOR: output \(\overline{A+B}\).
Second gate is a NOR with both inputs joined, which acts as a NOT: output \(A+B\).
Last gate is a NOT: output \(Y=\overline{A+B}\).

This is the NOR gate.
