Half subtractor: Learn how to design and

Learn how to design and implement half subtractor and full subtractor circuits using logic gates and K-maps. Half subtractor subtracts two bits, while full subtractor subtracts three bits with a borrow output. Half subtractor is a combinational logic circuit intended to perform the subtraction of two single bits and generate the output. A subtractor circuit with two input variables as A and B displays two outputs i.e Difference and Borrow. The block diagram of a Half subtractor is as shown below: A half subtractor is a combinational logic circuit that calculates the difference of two binary digits and produces a borrow output. Learn how to design, simplify, and use a half subtractor in digital electronics with examples and diagrams. Here, we will discuss the implementation of a half subtractor using NAND gates. But before that lets have a look into the basics of the half subtractor. What is Half Subtractor? A half-subtractor is a combinational circuit which has two inputs and two outputs where one output is difference and another is borrow bit.
