The i/p variables of the half adder are termed as augend bits & addend bits, whereas the o/p variables are termed as sum and carry. The half adder is used to add two i/p bits and generate a sum and carry which are called as o/ps. The simplest design of half adder is shown below. The carrier signal specifies an overflow into the following digit of a multi-digit addition. Half adder has two o/ps such as sum and carry, where the sum is denoted with ‘S’ and carry is denoted with ‘C’. The half adder circuit is used to sum two binary digits namely A and B.

4 DESIGN PROCEDURE The design of the combination circuits begins with a description of the purpose of the design and culminates in a logic circuit diagram or a series of Boolean functions from which the logic diagram can be derived. The applications of adder circuit are, adder circuits are not only used to add binary numbers, but also used in digital applications such as address, table index, decoding and calculation etc. Inspection of the variations of the truth table for A, B, C, F 1, and F2 reveals that it is identical to the full-adder truth table given in Section 4. When the one’s or two’s compliment are being used to specify negative numbers, it is small to alter adder to subtractor.A more complex adder is used to represent other signed numbers. This circuit has two outputs carry and sum.
Therefore, the computed sum will be A + B + SUB A + B. Note that when the control signal SUB is low, A A B B Cin 0. An Adder subtractor can be achieved by using the following circuitry. It is the basic building block for addition of two single bit numbers. In order to transform a normal adder IC into a subtractor, you need to invert the second operand ( B) and add 1 (by setting Cin 1 ). The half adder circuit is designed to add two single bit binary number A and B.
The main purpose of these addresses are used to add the different formats like XS-3, binary coded decimal (BCD) and gray code. Half adder is a combinational logic circuit with two inputs and two outputs. A typical adder circuit generates sum and carry as the output. Adder circuits are not only used in ALUs, but also used in various processors to calculate increment or decrement operations, table indices, addresses, etc. In electronics, adder circuit performs addition of the binary numbers.in various computers and other types of processors.
