Assume negative number representation systems with 7 bits word length (word length is the number of digits or bits used to represent a number including the sign digit). Perform the following tasks. if it is not possible to find the answer because of limited number of digits (overflow), write N/A 1. In sign and magnitude binary representation, 4110 is 2. In 2's complement binary representation, - 2910 is N2 = 3. In 1's complement binary representation, - 2910 is 4. Using 2's complement representation, we can represent any number between N1 = ..... and .... (write the answers in decimal) 5. Using 1's complement representation, we can represent any number between N1 = ....... and N2 = ....... (write the answers in decimal) 6. In 2's complement, N, = 1001001, and N, = 01011002. Ni + N2 (in binary) 7. In 1's complement, N = 1001001, and N, = 01011002. N, + N2 = (in binary) 11 8. In 2's complement, N, = 0111101, and N2 = 01011012. N + N2 = (in binary)
