The implementation of the Xor gate in the Nissan

• How many gates are used in the implementation of the Xor gate in the Nissan and Schocken textbook? • Present your implementation to the Xor chip. How many gates are there in your implementation? • Please use engineer's logic and your textook to answer the following: • Can you think of a more efficient implementation? • Efficiency is not necessarily the number of gates used. It's all about "following the money." In other words, what does it cost to implement a new gate?
