Extracted text: 4. Create a table which shows the outputs of the circuit in signed decimal representation when the inputs change from the largest possible number to the smallest number. When the carry is discarded, the result is 4-bit long. Which combination of inputs result in an overflow. Inputs Outputs (According to the Mode) M1=0, Mo=0 M1=0, Mo=1 M1=1, Mo=0 Overflow Overflow В-А Overflow A A+B А-В (Y/N) (Y/N) (Y/N)
