WebThe addition and subtraction operations can be combined into one circuit with one common binary adder. This is done by including an EX-OR gate with each full adder. A 4-bit adder-subtractor circuit is shown in fig 4. The mode input M controls the operation. When M = 0, the circuit is an adder, and when M = 1, the circuit becomes a subtractor. WebThe operation of 4-bit Binary adder / subtractor is similar to that of 4-bit Binary adder and 4-bit Binary subtractor. Apply the normal bits of binary numbers A and B & initial carry or borrow, C 0 from externally to a 4-bit binary adder. The block diagram of 4-bit binary adder / subtractor is shown in the following figure.
