2 to 1 Multiplexer

  1. Oct 23, 2013 #1
    Consider f = w1w2! + w1w3 + w1!w2 +w1!w3! Use the truth table to derive a circuit for f that uses a 2-to-1 multiplexer

    I have the truth table, that part is easy. The problem I'm having is what exactly are they EVALUATING to get the f?

    Like I said I have the truth table of 3 input, but I don't know how to evaluate for the f. I know it's like a 0 and a 1. But where do I plug in each etc.

    Can you please post your work? Show us the truth table, and show what a 2:1 MUX looks like...
