Question 4 In the lectures, I mentioned that 2's complement overflow can be detected if the carry bit coming into the most significant bit adder is different than the carry bit going out of the most significant bit adder. a) Show two examples where this is the case. In your first example, the carry bit coming into the MSB adder should be 1 and the carry bit at the output of that adder should be 0. In your second example, the carry bit coming in is 0 and the carry bit leaving is 1. b) Explain why this rule guarantees that overflow has occurred
