The word "single-bit" confused me.If you are only allowed to use MUXes, then why do you have two other gates there. What are the actual rules?
On what basis do you claim that there's no carry in. You are asked to make a full adder and not a half adder. What is the difference between the two?
yes thank youOne mux is used for the sum and the other mux is used for the carry out. There are three inputs so you need 8:1 muxes. Does that help?
