    Hi.
    I am new to circuits so sorry if this seem simple.
    I have this homework that I am stuck with and would appreciate some assistance. Basically, what I need to do is design a 32-bit comparator made up of 2-bit cascaded comparators.
    But I am not sure how to turn a 2-bit comparator into a cascaded comparator and was wondering if somebody could explain to me how this is done.
    Here is what my design for the 2-bit comparator looks like.

    So if anyone could explain to me how to cascade this I would greatly appreciate it.
    Thanks.

    It would be helpful if you provided the corresponding truth-tables and context of what you are doing, as well as labeling the outputs on your diagram.
