    So I am building a 2 bit Ripple Carry Adder and the first 1 bit adder I already have completed using logic gates.. Now i'm suppose to build the other adder using a 4:1 Mux and i'm a little confused where to start..


    For the Mux I have 3 inputs that I need to use..

    Cout from the first 1bit adder and then A and B

    and then I'm suppose to have 2 outputs.. Cout from the second adder and S but the Mux only has 1 output...


    any ideas?
