Explain the binary adder-subtractor circuit with suitable diagram. [5]
A binary adder-subtractor is a combinational circuit that can perform both addition and subtraction of binary numbers using a single circuit, controlled by a mode select input. --- The circuit uses the concept of 2's complement subtraction: A - B = A + (2's complement of B) = A + (1's complement ...
