3 3 Design of Half Subtractor & Full Substractor

Half Subtractor and Full Subtractor are combinational logic circuits used to perform binary subtraction in digital electronics. A Half Subtractor subtracts two binary bits and produces Difference and Borrow outputs, while a Full Subtractor subtracts three binary bits, including a borrow-in, and generates Difference and Borrow-out. These circuits are fundamental building blocks for implementing binary arithmetic operations in digital systems.
