However, the circuit diagram shows the logic gate connected directly to the current input in.

Why is the current input used instead of a stored previous input? Should an additional flip-flop be required to store the previous input value?

    I don’t know how to handle the last row of truth table where X_old and Y_old are both 1 and everything is marked X.
