Part 1 - give the truth table for an XOR port

part 2 - implement the results (from part 1) using only NOR ports

2. Relevant equations

3. The attempt at a solution

So far I have tried combining NOR gates and have even used single input NOR gates (effectively turning them into NOT gates), but I whatever combination I use I can't see how to make the circuit behave like an XOR gate/port.

I always end up with 2 signals going into a final NOR gate that could be 0&0, 0&1, 1&0 or 1&1, but by definition I thought that an XOR will only have a '1' signal if and only if we have 0&1 OR 1&0 - Which is not the same as a NOR gate. So I can't see how using only NOR gates can work.It would be easy to make the XOR using NOT and AND gates, but I'm not so sure about NOR gates.

Can anyone suggest something? a hint would be appreciated

Thanks
