    What is your question?
    What have you done so far to solve the task?

    i have managed to identify X Y Z being A.B', A'.B, A'B' respectively.
    Have slightly drown a circuit diagram but my doubt is on the relationship of Z is it supposed to be attached to the output of X and Y?

    You can either define Z = f(A,B), as you did, or Z = f(X,Y) as you asked.
    Using the correct boolean operations both methods will produce the right output.
    The difference is in the timing: Assume some arbitrary runtime T for the calculation of a boolean function f(). What is the runtime for Z = F(A,B) expressed in terms of T and what is the runtime of Z = f(X,Y), also expressed in terms of T? Hint: X = f(A,B) and y = f(A,B).
    f() indicates the required boolean operation which are of course different for each output.

    Hello,

    Here is the question in full:

    bit220_questions.png

    In the case A=B , both are either 0 or 1.

    yeah i was thinking in that question they have only picked were both are 0 to reference the relationship where A=B.
