Introduction
 Adders are digital circuits that carry out addition of numbers.
 Adders are a key component of Arithmetic Logic unit.
 Adders can be constructed for most of the numerical representations
like Binary Coded Decimal (BDC).
 Adders are also used in table index calculation, address decoding etc.

Adders Are Classified Into TwoTypes
 Half Adder and Full Adder.
 The half adder circuit has two inputs:Aand B.
 It add two input digits and generate a carry and sum.
 The full adder circuit has three inputs: A, B andC.
 It add the three input numbers and generate a carry and sum.

• What is Half Adder Circuit ?
 The half adder adds two binary digits called as augend and addend.
 Half adder produces two outputs as sum and carry.
 XOR is applied to both inputs to produce sum.
 AND gate is applied to both inputs to produce carry.

• Half Adder TruthTable
 1-bit adder can be easily implemented with the help of the XOR Gate for the output ‘SUM’and an
AND Gate for the ‘Carry’.

• What is Full AdderCircuit ?
The full adder adds 3 one bit numbers.
Where two can be referred to as operands.
One can be referred to as bit carried in.
It produces 2-bit output, and these can be referred to as output
carry and sum.

• FullAdder
 The output carry is designated as C-OUT and the normal outputis designated as S.

• The relationship between the Full-Adder and the Half-Adder:
Half adder produces results and full adder uses half adder to produce
some other result.
Similarly, the Full-Adder is of two Half-Adders.
The Full-Adder is the actual block that we use to create the arithmetic
circuits.
