2. (10 points) An n-bit 2-1 multiplexer is multiplexer with two inputs each consisting of n-bits and one n-bit output. Design a 4-bit 2-to-1 multiplexer. Make sure to label all inputs and control signals appropriately. The table below gives the truth table of 4-bit2-1 multiplexer with inputs A3..0, B., control signal S, and output Out3.0 (input A connected to first input and input B connected to the second S Out3..o 0 A3..0 1 B3..0
