Consider the 12 bit number A-0110 1001.0011 which is in 2's complement representation. Alse. imagine number B as another 12 bit number in 2's complement representation. Assuming that know that A+B results in overflow, answer the following questions: * What is the sign of A? * What is the sign of B? * What is the B with the smallest possible absolute value? Represent B in both Z's complement and sign and magnitude decimal representation.
