Question

Computer Organization and Architecture-Explain too please :)

Input A ONOG Input B Ono OUTPUT 12 3 -6 Input C Ono a. Without using the tool, just based on observing the diagram and reading the web site's definitions of the symbols, write out the algebraic equation implemented by this circuit. Do not try to simplify the equation. I started at the output, replacing input numbers with expressions step by step, right to left. For example, just working backwards from the output to input 9, then 5, then 1 and then to input A, we notice the following: The output is #13, and we can see that 13 = 9 AND 10. Also: 9 = 5 OR 6 5= 1 AND 2, and 1 and 2 are connected to Inputs A and B, so we know input #5 is A AND B. So since 95 OR 6, we know 9 = (A AND B) OR 6. And we now know that 13 = ((A AND B) OR 6) AND 10. Continue until you have only inputs A, B, and C, and operators like AND, OR, NAND, NOR, and XOR. You should generally write out your equation to follow the elements from left to right, top to bottom. b. Build a truth table for this circuit. I've completed the inputs and the first equation sub-part.
