Which one of the following circuits is NOT equivalent to a 2-input XNOR (exclusive NOR) gate?
Attempted by 664 students.
Show answer & explanation
To determine if a circuit is equivalent to a 2-input XNOR gate, follow these steps:
Step 1: Identify the two inputs and the output of the circuit.
Step 2: Trace the signal flow through each gate to determine the output for every possible input combination.
Step 3: Construct a truth table for the circuit, listing the output for inputs (0,0), (0,1), (1,0), and (1,1).
Step 4: Compare the circuit's truth table to the standard truth table of a 2-input XNOR gate.
Step 5: If the truth tables are identical, the circuit is equivalent to an XNOR gate. If they differ, it is not.
Apply this method to each circuit to determine which one does not match the XNOR function.
