Adders are one of the main components of majority of circuits and find their application in ALU’s, microprocessors, DSP processors.1-Bit Full adder can be used to implement other circuits such as ...

We append another XOR gates to alter Subtrahend. The reason is, in logic subtraction is adding 2’s complement of a number. So that is why we employed a full-adder and XOR gate to subtract. Lastly as ...
