    Design a simple comparator circuit that would compare between 2-bit numbers, such as 01 and 10, where the output could be a 1 indicating equality, or 0 indicating inequality of the two numbers.

    Any help would be highly appreciated.

    Thank you in advance

    I would use logic gate for that because compartors are analog

    How about using exclusive OR gates?
