1. The problem statement, all variables and given/known data Draw a diagram to show how to implement a 8 to 1 multiplexer with two 4 to 1 multiplexers and a 2 to 4 binary to decimal decoder. 2. Relevant equations / 3. The attempt at a solution I know that I'm going to need another select line (S2) since an 8 to 3 multiplexer has 3 select lines but I've been struggling with the decoder. I have no idea what purpose the decoder should serve. Any help would be appreciated :).
