In summary, multiplexers are digital circuits that select one input signal and output it as a single output signal. They are controlled by select inputs and are used for functions such as data routing, signal switching, and data compression. They have advantages such as simplicity, efficiency, and versatility, but also have limitations such as only being able to output one value at a time and becoming more complex with more inputs and outputs.

Since you're allowed to use 4:1 multiplexers, there is a 3-gate solution. Your last gate (based on X3) is fine. Here's my final clue: How can a truth table be implemented with a multiplexer?
1. What are multiplexers and how do they work?
Multiplexers, or MUX, are digital circuits that select one of several input signals and outputs it as a single output signal. They have multiple select inputs and a single output, and their operation is controlled by the select inputs. The selected input is transmitted to the output, while all other inputs are ignored.
2. What are the benefits of implementing a function using multiplexers?
Multiplexers are a simple and efficient way to implement logical functions. They require fewer components compared to other methods, reducing the complexity and cost of the circuit. They also allow for multiple functions to be implemented using a single multiplexer, making them versatile and space-saving.
3. What are some common applications of multiplexers?
Multiplexers are commonly used in digital systems for data routing, signal switching, and data compression. They are also used in digital logic design, such as in implementing arithmetic and logical operations, and in electronic communication systems for multiplexing multiple signals onto a single channel.
4. How do you design a circuit using multiplexers?
The first step in designing a circuit using multiplexers is to determine the number of inputs and outputs needed for the desired function. Then, the appropriate size of the multiplexer can be selected. The select inputs must be configured to correspond to the desired output, and the remaining inputs can be connected to the appropriate logical values to implement the function.
5. Are there any limitations or drawbacks to using multiplexers?
One limitation of using multiplexers is that they can only output one value at a time, so they are not suitable for implementing functions with multiple outputs. Additionally, the more inputs and outputs a function has, the larger and more complex the multiplexer circuit becomes, which can lead to slower operation and increased power consumption.
