Best ResponseYou've already chosen the best response.1I think first, create a 2to1 multiplexer with logic gates, 2 inputs, and 1 output (don't get select functionality). What relationship do you see with regard to number of inputs versus selection lines for the output? The above is just to ensure you understand a multiplexor, if you already understand them well, then the exercise is decent review.

Best ResponseYou've already chosen the best response.1The 8to1 requires 8 inputs, 1 output. How can you accomodate 8 inputs with the constraints you have: 2to1 MX, and 4to1 MX ? This question conveniently uses numbers that are powers of two... Once you have designed for the 8 inputs, you should then see how you can further design for generating only 1 output.

Best ResponseYou've already chosen the best response.0You would use two 41 multiplexers that would then feed their outputs in to a 21 multiplexers this should give the equivalent of a single 8+1
