4. Consider the following circuit diagram, 4.a Convert the circuit into a Boolean Algebra expression (e.g. B+ AC is a Boolean algebra expression); write each expression next to the appropriate gate in the diagram. (4 gates, so 4 expressions) Use the Boolean algebra notation when you are writing your expressions: i.e. (for not A); AB (for A and B), A + B (for A or B), AB (for A xor B) 4.b Evaluate the output of each gate, including the final gate, given that A-1, B-1 and C-0. Use the diagram to show your evaluation of each gate. Paste the photo of the circuit wi he Boolean expressions and the evaluation of the output of each gate into the omework document in order to get credit
