I've been trying to do this problem for the past 5 hours... I can't figure out how to do it. I've looked at online references and posted powerpoints about multiplexers, but I've never found any help with solving a problem like this.
I attempted to draw out the decoder with two inputs S0 and S1 going to AND gates with lines I0-I3 going into those AND gates then the outputs of those AND gates OR'd w/ each other to represent the inside of the multiplexer, but after I got some sort of a visual representation of the problem, I encountered a problem with only 8 outputs 0 - 7 excluding 8 and 9 because in the problem, it says S(0,2,3,4,5,7,8,9) which is representative of the SOP based on 16 outputs 0 - 15. Then I became puzzled how to get outputs 0 - 15 with only 3 bits, I(n) S1 and S0, which is impossible. You can't make a number greater than 7 with three bits...
So I decided to try to make a K-map of the SOP given, but then I encountered the problem if you had a 4x4 K-map then you're missing a fourth variable to represent the most significant place value of the numbers from 0 - 15.
Then I got stuck and tried reviewing more resources...
Please anyone... your help would be greatly appreciated. x_x
