    1. The problem statement, all variables and given/known data

    1. Convert the following NAND-NOR circuit to simplest AND-OR circuit (bubbles allowed) such that the output gate is an AND. Then, convert the resulting circuit back into a NAND-NOR circuit (no bubbles) such that the output gate is a NOR.

    2. Relevant equations


    3. The attempt at a solution

    My solution is drawn in two parts, part a) and b).

    For part a) I believe I got the simplest AND-OR circuit possible with an AND gate output.

    For part b) I am unsure if the circuit is as simple as possible, but I managed to get a NOR output.

    My work is shown below:

    Do these look okay?

    Thank you.

    Looks right.
    For clarification, I would swap the two NOT for A and B in the last diagram (so the upper gate keeps the same meaning as before), but that does not change how the circuit works.

    For that matter, the upper left combination is an XOR:
