& Applications The schematics of Full adder are shown in the figures below: Full Adder using individual half adders A full adder can be implemented using two half adders in cascaded setup. It consists of 3 inputs. We can use adder as subtractor if we make Cin input as a selector between addition and subtraction. Half adder can add only two 1-bit A full adder is a digital circuit that performs addition. Full adders are implemented with logic gates in hardware. A full adder adds three one-bit binary numbers, two operands, and a carry bit. The adder outputs two numbers, a sum and a carry bit. Then the full adder is a logical circuit that performs an addition operation on three binary A and B. The 'diff' and 'borrow' are two output states of the half subtractor with the above truth table. The SOP form of the Diff and Borrow is as follows: Diff=A'B+AB'. Borrow = A'B. 2.Implementation of Half Subtractor using NOR gates : Total 5 NOR gates are required to implement half subtractor. 3.truth table for full subtractor :- Aim: To design and implement combinational logic circuits like half-adder, full-adder and half-subtractor using NAND gates. Apparatus: 1. Design procedure: The design of combinational circuits starts from verbal outline of the problem and ends in a logic circuit diagram, or a set of Boolean functions from which the logic diagram can be Aim : - To realize half/full adder and half/full subtractor. i. Using X-OR and basic gates ii. Using only nand gates. Apparatus Required: - IC Trainer Kit, patch chords , IC 7486, IC 7432, IC 7408, IC 7400, etc. Procedure: - 1. Verify the gates. 2. Make the connections as per the circuit diagram. 3. Half subtractor is used to perform two binary digits subtraction. In half subtraction, the process of subtraction is similar to arithmetic subtraction. In arithmetic subtraction the base 2 number system is used whereas in binary subtraction, binary numbers are used for subtraction. The resultant terms can be denoted with the difference and borrow. a Full Adder using i Basic logic gates and ii NAND gates b Full subtractor using from ENGINEERIN ELECTRICAL at Rashtrasant Tukadoji Maharaj Nagpur University.

It is used for the purpose of subtracting two single bit numbers. It also takes into consideration borrow of the lower significant stage. Thus, full subtractor has the ability to perform the subtraction of three bits. Full subtractor contains 3 inputs and 2 outputs (Difference and Borrow) as shown-.
