Answer #1

To obtain the 2's complement of a number:
First obtain it's 1's complement( i.e interchanging 0's to 1's and 1's to 0's for it's binary number) & then add 1 to that 1's complement

For Binary addition

Addition Sum Carry
0+0 0 0
0+1 1 0
1+0 1 0
1+1 0 1


From the above Result it is having 8-bits only. So there is no overflow Occurs

Design a 4-bit adder-subtractor circuit using the 4-bit binary Full adders (74LS83) and any necessary additional logic gates. The circuit has a mode input bit, M, that controls its operation. Specifically, when M=0, the circuit becomes a 4-bit adder, and when M=1, the circuit becomes a 4-bit subtractor that performs the operation A plus the 2’s complement of B.Where A and B are two 4-bits binary numbers. That is, * When M=0, we perform A+B, and we assume that both...
