How do you implement a circuit using MUX?
How would one go about implementing a circuit utilizing Multiplexers (MUX)? Could you walk me through the process from start to finish, including the considerations that need to be made in terms of selecting the right MUX, the design of the logic, and the actual implementation steps? Additionally, how does one ensure that the circuit functions correctly and efficiently after implementation? What troubleshooting steps might be needed if issues arise?
