I got it working.



I just need to make it slightly neater, lol.

Thanks for your help Eugine <3.

Hi Eugene,
Thanks for your reply.

I've taken your advice to constructing circuits for P1 and P2 separately.
I've also constructed the rows that output 1 from the truth table.
I'm not sure why your example for the first row has the two NOT gates. It works without them.

Here screenshots for the ...

Hi guys,

As you can see from the picture the first 5 combinations from the truth table work, however the rest don't.

I'm still relatively new to logic circuits so any advice is greatly appreciated.

me luv u long ...
