Full subtractor: Learn how to design and implement

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. Introduction Subtractor circuits take two binary numbers as input and subtract one binary number input from the other binary number input. Similar to adders, it gives out two outputs, difference and borrow (carry-in the case of Adder). There are two types of subtractors. Half Subtractor Full Subtractor 1) Half Subtractor The half- subtractor is a combinational circuit which is used to perform subtraction of two bits. It has two inputs, A (minuend) and B (subtrahend) and two outputs Difference ... Half subtractor Before proceeding to the topic, you have to know about Binary subtraction. Learn How to subtract two binary numbers. The half- subtractor subtracts two bits and produces an output as difference and borrow. It needs two binary inputs (subtrahend bit and minuend bit), two binary outputs (difference and borrow) and combination of logic circuit.
