(Word Problem) Design a combinational logic subsystem with three inputs, 13, 12, I1, and two outputs, 01, 00. that behaves as follows. The outputs indicate the highest index of the inputs that is driven high. For example, if 13 is 0, 12 is 1, 11 is 1, then 01, 00 would be 10 (i.e., 12 is the highest input set to 1).
(a) Specify the function by filling out a complete truth table.
(b) Develop the minimized gate-level implementation using the K-map method.
(c) Develop an implementation using two 4:1 multiplexers.
(d) Compare your implementation for 1(b) and 1(c). Which is better and under what criterion?
