Half Adder:
The Half Adder is the combinational circuit that adds the two bits and generates the Sum of two bits and Carry bit as an output.
The logic circuit of the Half adder consists of one two-input XOR gate (Sum output) and one AND gate (Carry Output).
The Boolean expression of Sum and Carry output of Half Adder:
S = A (XOR) B
C= AB
The half-adder circuit can add two one bits numbers, but if there is an incoming carry from the previous addition then it cannot be added using the Half adder.
Full Adder:
The Full-adder is the combinational circuit that adds the two bits and the incoming carry bit and generates the Sum bit and Carry bit as an output.
The Boolean expression of Sum and Carry output of Full Adder:
S = A (XOR) B (XOR) Cin
Cout= AB + BC + AC
Cout = AB + Cin [ A (XOR) B ]
The Full Adder circuit can be implemented using the two Half Adders and one OR gate. In this video, the design of Full Adder using Half Adders is also explained.

This video will be helpful to all the students of science and engineering in understanding the Half Adder and Full Adder Circuits, and how to design a Full Adder using Half Adders.

hi. tnx for learning. how do u create this videos? the table, elements and formulas?
yes please tell me which software you are using for making these videos ... please
I ' m korean and i m here to see your video beacuse i m learning this in high school..my school teaches this content in subject, computer..i just want to say thank you for uploading this video you save my life...i spend so much time on this, now finally you made me be understood
This place is a goldmine
In search of gold I got a diamond
And I'm the pro-est gold miner
For reallll😭
Yes bro
Would just take a moment to give much thanks for this interesting explanation, i'm sure it's gonna help so many people out there. 💌
Thank you so much for this perfectly outstanding explanation! I finally understand half and full adders after watching so many YT videos and going through countless PPT slides and textbook pages. All of them either didn't explain anything and encouraged us to just memorize the truth tables, or attempted to explain this topic but ended up being convoluted. This is what real teaching is! May God bless you, and thanks again.
Here is not only about being a Genuis, this is real teaching 🙏🏿❤️
This is a better explanation than my professor’s explanation
That's why lectures r gods , especially who explains in TH-cam 🙏🏻
Thanks for such a great video. It was so clear and I was even to draw the Full Adder and simplify some of it myself!
Your content is so helpful, thanks so much!
My exam is in 2 hour's band I'm watching this channel is too satisfying 😌
Which
this video was so well done, such a good explanation thank you!!!
The world's best teacher thanks
Thank you sir
Awesome explanation
Thanks you so much sir, explanation is outstanding ,for making the videos once again thank you sir
Great video. Really Helpful 🙂
Finally Got the useful video☺️❤️
Thank you sir
Excellent mind blowing explanation bro. May god bless you . thank you so much for your video s. 🎉🎉
Excellent class 👌🏼👌🏼
Excellent explanation
excellent teaching👌
I can't thank you enough.❤️
Thank you sir for that half and full adder
Thank you for the video.. Very useful
Thank you sir for this amazing video
Legendary explanation
Excellent explanation sir ❤
very good and informational video, truly explained it very well
Thanks for the video! But i have a question in minute 6:30 : Can we instead of doing the normal form directly jump to in which scenarios, for example, Sum is 1? we have C.in + B + A + ABC.in. Same for the C.out
I saw you doing something like that in the enconder video. Why do we do diffferent here?
Last question. If doing like I said, can we manipulate the result to xor or xnor gates as in the video?
nice video bro keep teaching us
Thank you very much 👍
Thank you ! thank you !!
Wow..
Awesome explanation...🔥🔥
Thank u so much sir 🙏
Thank you so much sir
Mind-blowing explain..!
just awesome 😀
Sir.....
When a BJT functions as an amplifier, which of the following is controlled?
Collector current, emitter current, base current or all ?
base
Base current because it depends on BetaDC.
Thank you 👍
thanks a lot. u r a life saver.
Great explanation.
Nice 👍
Thanks a lot
Thank you

Thanks
I have a question...
Jab apny k map use kya to us me jo values put ki wo pos me hain lekin apny usy sop me likha hoa tha or 1 se represent kya...
Yhan se smjh nhi ai please thorra explain kardain
Fantastic 👌👌
Super sir..thank u so much

super sir
That's what I am searching .
Thanks sir ❤❤
Thank you so much 🙏
Nice explanation
Tomorrow is my exam and I am fully prepared 🙏
You saved me 😂
Sir when we wrote carry in two different fashion by equating them why are we getting that or gate equals exor
See this is the special case, where we are getting this condition. That means, using either OR gate or the XOR gate, we can get the same result. If you see the carry output, then it is equal to 1 when both A and B are 1, or when Cin is 1 and either A or B is 1, or all three inputs are 1. So definitely, using OR gate, this condition will get satisfied. If we use the XOR gate, then whenever A = B = Cin = 1 then Cin (A ⊕ B) will be 0. But since both A and B are 1, so first term (A.B) will be 1. And in this way, using both XOR gate, or the OR gate, we are able to produce same result. I hope, I was able to convey the reason for that. In case, if you still have any doubt then let me know here.
@@ALLABOUTELECTRONICS thank you so much sir. I got it. U da 🐐
class 11th students wo took computers for granted
sir is something wrong here 8:59 bcoz the simplified answer and the value you took for Cout don't match i don't have an idea about what happened could you please explain
Both expressions of Cout are correct. At 9:00 onwards, I have explained that how we can get the second simplified expression from the first expression. The expression has been written from the truth tables. ( It is the summation of all the mimterms for which the output is 1)
I hope, it will clear your doubt.
@@ALLABOUTELECTRONICS thank you sir
in full adder the output of A XOR B and Cin was again sent to another XOR gate. Why?
It is given to the OR gate. ( Just to generate Cout)
Please check it again at 11:23.
If you still have any doubt then let me know here
Sir Sir I am a beginner now. And may want to become electronic engineer. Where do I start and what is my path? What is my path for electronic engineer. I were saw your playlist but I am very confused where to start. Technology playlist?
Start with the basic electronics playlist.

How does sum equation and carry equations are created
It is created from the truth table. It is the summation of all the minterms ( input combinations) for which the output is 1. 6:30 onwards I have explained that.
6:29 Where from boolean expression comes
From the truth table, it is the summation of all the minterms for which the S is 1.
I hope, it will clear your doubt.

Sir what is combinational circuit ???
It is the digital circuit which is made up by combining different logic gates. In the combinational circuit, the output of the circuit depends only on the present inputs of the circuit. (There is no feedback from output to input side)
@@ALLABOUTELECTRONICS sir can you briefly explain the term " feedback " , I'm confused
Please check the video on Sequential Circuits. You will get the idea.

@@ALLABOUTELECTRONICS Thanks
sir why we cannot give 3 inputs in Exor gate
It can be implemented using 3 input XOR gate. but as I have shown in the video, the sum expression can also be represented as AB + Cin. A ( XOR) B.
So, using the some part of the carry generating circuit, the sum generating circuit can be designed. And in this way, number of logic gates used in the circuit can be reduced.
Just to show that, it was represented using two XOR gates.
I guess.... I dropped in a goldmine
And I in problems

I am getting brain damage from the way you speak, but thank you for the information

Did not undrstand at 7:20 😢
For further simplification, B ( XOR) Cin is assumed as another variable X. That means now, B ( XOR) CIN = X and [ B ( XOR) CIN ] ‘ = X’. And the overall function will become A’.X + A.X’. And that is equal to A( XOR) X. Or it can be represented as A( XOR) B ( XOR) CIN.
why do so many indians speak english with the weird pause and pitch raise in random spots? Like:
this is the sum and the?.... *carry*
A is equal to B and ?.... *C bar*
why do they pause in random?... *places*
maybe it is for?... *suspense*
but if it?... *is then*
it's not?... *working*
There is no specific reason.Its just a weird part of our accent.
maybe because english isnt their first language? lol, it happens because non native speakers tend to apply the speech rules and sounds of their native language while speaking other languages like english
