    The question is as follows :

    - Show the subtraction of two 2-bit numbers, A1 A0 and B1 B0 using 2's complement. Show how the parallel 2-bit binary adder can be converted into a parallel 2-bit binary subtractor.

    P.s : If the circuit is to be implemented, specify the restrictions in the circuit and suggest how the circuit is to be implemented such that it is hardware efficient.

    Thanks in advance.

    When you created the thread, it gave you a list of similar threads and asked you to look at those to see if they answered your question. Did you do that?

    One of the threads was probably this one. A quick glance through it suggests that it may well have everything you need. If you do a search of the forum, you will find several others since this is a common homework problem. So go look at those for a bit and then come back and post any questions that are not adequately answered. The best place to do so would actually be as a response to one of those other threads, provided it is reasonably in line with the original topic of that thread.
