Question: a. Given two n-bit twos complement numbers, prove that an addition overflow occurs if and only if the carry into the most significant bit position

a. Given two n-bit twos complement numbers, prove that an addition overflow occurs if and only if the carry into the most significant bit position and the carry out of the most significant bit position are different.

b. Consider now the sign-magnitude representation. Define the meaning of overflow in this representation and suggest an overflow detection mechanism.
