Made Easy Digital Logic Combinational Circuits Gate
To design a binary subtractor circuit, 1’s complement procedure is better,because it uses less hardware. 2’s complement procedure is better,because it uses less hardware. Binary ‘0’ is having unique representation in sign 1’s complement notation. Binary ‘0’ is having unique representation in sign 2’s complement notation.
