1. (30 points) Applications of Logic in Computer Architecture A very common circuit in computers is called a multiplexer. (A multiplexer is like a switch on a railroad, except that it helps route electrical signals rather than trains. For example, sometimes the data going to memory will come from an arithmetic calculation, and sometimes from an input buffer. A 2-value multiplexer controls which data gets sent to memory.) A 2-value multiplexer has three inputs, two for data and one for control. The output is equal to the first data input when the control input equals zero, and the output equals the second data input when the control is one.
