The EXCLUSIVE – NOR gate is equivalent to an _____ gate followed by an invertor. A. OR B. AND C. NAND D. XOR E. None of the above

The correct answer is: D. NAND

An exclusive-NOR gate (XOR) is a digital logic gate that implements logical exclusive OR. It produces a high output (1) if either, but not both, of its inputs are high. If both inputs are low, the output is low.

A NAND gate is a digital logic gate that implements logical negation followed by logical AND. It produces a high output (1) only if both of its inputs are low. If either input is high, the output is low.

A NAND gate followed by an inverter is equivalent to an XOR gate. This is because the inverter inverts the output of the NAND gate, which changes a high output to a low output and a low output to a high output. This results in an output that is high if either, but not both, of the inputs are high.

The other options are incorrect because they do not produce the same output as an XOR gate. An OR gate produces a high output if either or both

of its inputs are high. An AND gate produces a high output only if both of its inputs are high. A NOT gate inverts its input, so it produces a high output if its input is low and a low output if its input is high.
