Learn how to perform binary subtraction using half and full subtractor circuits, their logic diagrams, truth tables, equations and Karnaugh maps. Find out the applications and common ICs for making subtractors in digital electronics. A subtractor is a digital logic circuit in electronics that performs the operation of subtraction of two number. Subtractors are classified into two types: half subtractor and full subtractor. The half subtractor (HS) circuit has two inputs: A and B, which subtract two input binary digits and generate two binary outputs i.e. borrow and difference. 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. A half subtractor is a digital logic circuit that performs the binary subtraction of two single-bit binary numbers. It has two inputs, A and B, and two outputs, Difference and Borrow.
