by using 4 NCL gates we can design or implement a half adder.gates used in half adder are TH12[1 GATE],TH22[1 GATE] and TH24COMP0 [2 GATES].this NCL have a concept of DUAL-RAIL.output we get for this are S0,S1,Cout0,Cout1.
used as mux and demux , used for implement haff adder $ full adder, by program it
Use 4 NOR gates. For the 1st NOR gate, inputs should be x' and y For the 2nd NOR gate,inputs should be y' and x The outputs of NOR 1 and NOR 2 are taken as inputs of NOR gate 3 The output of NOR 3 is the complemented form of the output required, so, just complement the output of NOR gate 3 with another NOR gate and Viola!, you have your HALF ADDER OUTPUT PS:I have used a double rail logic, where both x:x' and y:y' are available
1 gate.
AND gate, INVERTER gate and OR gate. Hope this would help.

An adder is a digital circuit used to perform addition of binary numbers. It takes two binary numbers as inputs and produces a sum as output. There are different types of adders such as half adder, full adder, and ripple carry adder.
It is constructed with red and pale sandstone and granite.

Full adder circuit:Full adder reduces circuit complexibility. It can be used to construct a ripple carry counter to add an n-bit number. Thus it is used in the ALU also. It is used in Processor chip like Snapdragon, Exynous or Intel pentium for CPU part . Which consists of ALU (Arithmetic Block unit) . This Block is used to make operations like Add, subtract, Multiply etcA full adder adds binary numbers and accounts for values carried in as well as out. A one-bit full adder adds three one-bit numbers, often written as A, B, and Cin; A and B are the operands, and Cin is a bit carried in from the previous less significant stage.The full adder is usually a component in a cascade of adders, which add 8, 16, 32, etc. bit binary numbers.
In structural modeling of VHDL, the concept of components is used. In this model, the system to be designed is considered as a combination of sub structures. These sub structures are called components.For example, a full adder is a combination of two half adders and an or gate. Hence, the components used for designing a full adder arehalf adderOR gateInitially, these components are mentioned in the architecture of a full adder VHDL program. We call this as component initiation. Then the components are called onto the main program and used.Remember, we are using the functionality of the components in main program but we are not coding them in the main program. The code for the component programs will be present somewhere else in the project.Means, code them once and use them infinite number of times.
4 full adders will be used BCD is a 4 bit code. Each bit of the BCD number will be an input of each full adder. input 1 in first FA. 1 in second and 0 in the last to FA's
Generally speaking, gate valves in larger sizes are full bore unless you order a reduced port. You would always use a full bore gate valve for hot tapping purposes. or you would use a full bore gate vale for runinig a pig in pipeline.
A ripple carry adder needs a much less complicated circuit, than other adder topologies.

binary addition of two bits is called a half adder ,and of three bits is called a full adder to be more lucid in my explanation a half adder doesnot consider a carry generated from the previous added pair of binary numbers consider an example :- A=a1a2a3a4 + B=b1b2b3b4 = sum=s1s2s3s4 the actual addition procedure is a4 and b4 are added first then the sum is stored in s4 and the generated carry is added with a3 and b3 and the process continues so addition of a4 and b4 where there is no input carry is carried out by half adder and the addition of c1+a3+b3 is carried out by full adder. but practiclly the first situation a4+b4 can be considered as a4+b4+0 so all the addition can be performed by full adder it self truth table for both half adder A B s c 0 0 0 0 0 1 1 0 1 0 1 0 1 1 0 1 for full adder c1 A B s c 0 0 0 0 0 0 0 1 1 0 0 1 0 1 0 0 1 1 0 1 1 0 0 1 0 1 0 1 0 1 1 1 0 0 1 1 1 1 1 1 where s and c can be viewed as the sum and carry on solving the k-map for full adder and half adder we can obtain the fuctions of sum and carry
