1. The problem statement, all variables and given/known data Please see the attatched picture. 2. Relevant equations 3. The attempt at a solution I can complete the first part of the question, but i am not sure how i should do the second part. I would be grateful for a quick explanation or tutorial in how to do this part. I am aware of de Morgan's laws but cant seem to fully apply them to convert a whole circuit. Im not looking for an explicit answer, im looking for a technique in how to solve the problem. Thanks.
