1. DeMorgan's Theorem
2. Bubble Pushing
1) Backward:
–Body changes
–Adds bubbles to inputs
2) Forward:
–Body changes
–Adds bubble to output
📒 What is Boolean expression for this circuit?
3. Bubble Pushing Rules
•Begin at output, then work toward inputs
•Push bubbles on final output back
•Draw gates in a form so bubbles cancel
📒Exercise
