Learn how to design and implement half subtractor and full subtractor circuits for binary subtraction using logic gates, Karnaugh maps and common ICs. Compare the difference and borrow outputs, and the direct and 2's complement methods of subtraction. A full-subtractor is a combinational circuit that performs a subtraction between two bits, taking into account borrow of the lower significant stage. This circuit has three inputs and two outputs. Learn how to design and implement a full subtractor , a digital logic circuit that performs subtraction with borrow. See the truth table, logic diagram, and different gate combinations for FS. Full subtractor is a useful digital logic circuit that performs binary subtraction of two numbers while taking into account borrowing from a previous subtraction.
