I know how to create a full adder using a 4:1 mux with A and B as the select lines. However, now I need to create a full adder using B and Cin as the select lines.
the CoutMux and SumMux columns represent what the input lines would be for those 4:1 Multiplexers. I'm not sure how to get the values for the other inputs because the value of Cout and Sum is constantly changing while the value of A is the same.
Here is the original question if I didn't explain correctly:
Using two 4-to-1 MUXes, connect Cin and B to the control lines of the MUXES, and connect 1, 0, A, or A' to each input.
