Half subtractor and full subtractor lab manual

The full subtractor is a combination of X-OR, AND, OR, NOT Gates. In a full subtractor the logic circuit should have three inputs and two outputs. The two half subtractor put together gives a full www.doorway.ru first half subtractor will be C and A B. The output will be difference output of full subtractor. A Half-Subtractor: A half subtractor is a combinational circuit that subtracts two bits and produces their difference. It also has an o/p to specify if a1 has been borrowed. Designate the minuend bit by X and the subtrahend bit by Y. to perform X-Y we have three possibilities =0,=1,=1,=www.doorway.ru half subtractor needs two o/p’s. 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, X (minuend) and Y (subtrahend) and two outputs D (difference) and B (borrow). The logic symbol and truth table are shown below.

DLD LAB ASSESSMENT 1 REG NO: 20BCE NAME: Pratham Gupta www.doorway.ru a half adder, full adder, half subtractor and full subtractor circuits Aim: To design half and full adder and also half and full subtractor circuits and verify the truth tables. Apparatus: Sr No. Components Quantity 1. Voltage Sources 10 2. AND GATE 6 3. OR GATE 2 4. NOT GATE 3. Half subtractor: The half-subtractor is a combinational circuit which is used to perform subtraction of two bits. It has two inputs, X (minuend) and Y (subtrahend) and two outputs D (difference) and B (borrow). input Output X Y D B 0 0 0 0 0 1 1 1 1 0 1 0 1 1 0 0 D = X xor Y. B = X.Y Full subtractor. Full Subtractor Full Subtractor using Half subtractor. Comparing the equations for a half subtractor and a full subtractor, the DIFFERENCE output needs an additional input D, EXORed with the output of DIFFERENCE from the half subtractor. And the BORROW output just needs two additional inputs DA’ and DB.
