@The Hustlers As 1208 is written in its BCD xs code 3 and not in binary xs code 3. So that's why we can't '0100 0101 0011 1011' convert it to a decimal number because it is a invalid BCD.
Sir there u said 3-3-1-1 is self complementing, it's not is equal to 9. i know that Sir, I'm not a professional to teach you. But lakhs of people will watch in future. They'll get confuse. But I'm a huge fan your lectures. Thank you Sir.
1. 0100 1001 (convert to bcd, then add 6 to each digit individually) 2. 0100 1100 3. 0100 0101 0011 1011 4. Yes. consider revising the 2421 code again if you believe otherwise
i) 16 of xs-3 is = 0100 1001 ii)39 of xs-3 is = 0110 1100 iii)1208 of xs-3 is = 0100 0101 0011 1011 iv) 5-2-1-1 is 5+2+1+1 = 9 which is self-complementing code
For a code to be self complimenting, the sum of weights = 9 is a necessary condition but it is not sufficient. for eg. 7 2 -1 1 is not a self complementing code even though the sum of weights is 9.
for consecutive numbers or digits below 9 we got in excess 3 ....a 3 added number (eg :for 3 we got 6 ...) but for decimal numbers why we are not getting a 3 added to whole number but for each individual decimal digit....can anyone please help me
I have a doubt in xs-3 code of 658.When we look at xs-3code of 8 it is 1011 (11) but it is binary representation and we are operating BCD addition.Then should we add 0110 to 1011 to get correct answer? Plz help me.
In example ii) when we add '0011' to '1000' then it becomes '1011' i.e. greater than 9 . Then how the excess-3 code can again be converted to decimal? Will it be '9811' (in decimal)??
In example of 658 if there is carry generated for 8 do v have to pass it to 5 or jst ignore it or i shud ask shud i take carry forward to tenth digit code generated from addn of 3 in Ones digit code ???
Chandra Shekhar Chandu We are not expressing it as 9 8 11...the XS-3 representation is 1100 1011 1011...We dont need to convert it to decimal... He did it that for checking purpose... If u go through the lecture once again,u will understand

It should be 0110 1100
@@akshittomar2401 correct 😂
I think 3 rd one is also wrong because the number 1208: 12 =1100 and 08=1000 so 1100+0011=1111 and 1000+0011=1011. so anwer is 1511
@@padmasrikunigiri7092 No friend, you have to do it for each decimal digit because BCD codes works on binary digits of each decimal value.

For a code to be self complimenting, the sum of weights = 9 is a necessary condition but it is not sufficient.
for eg. 7 2 -1 1 is not a self complementing code even though the sum of weights is 9.
1) 0100 1001=49
2) 0110 1100= 6C
3) 0100 0101 0011 1011=453B
4)Self -complementing code
When to use 8421 and when 2421
How to differentiate this? both are BCD codes ?
Thankyou sir for your brilliant teaching🙂
9:20 gray code is also unweighted code which is self complementing
10:51 min 3311 is not self complemented
Sir 3-3-1-1 is not a self complementing code because here sum is not comming to 9
You made this subject so intresting for me 👍👍
for consecutive numbers or digits below 9 we got in excess 3 ....a 3 added number (eg :for 3 we got 6 ...) but for decimal numbers why we are not getting a 3 added to whole number but for each individual decimal digit....can anyone please help me
we have to convert the given no. into BCD representation first.
see the very initial part of the vedio.

Same question in my mind
Please anyone tell us
thanx neso it's late cus that lecture came in my exam in last Saturday
I think in the end the sum of 3-3-1-1 = 8 not 9 .So what we have to do? In that case
There it will be 3-3-2-1
You have explain it very well but there is an error.
As you said 3-3-1-1it is complement but, it is not the complement there it will be 3-3-2-1.
I have a doubt in xs-3 code of 658.When we look at xs-3code of 8 it is 1011 (11) but it is binary representation and we are operating BCD addition.Then should we add 0110 to 1011 to get correct answer? Plz help me.
10:31
He said that the example of self complementing code is 3-3-1-1 code... but its sum is 8.
Check the video description,
Sir mention that there was a problem to Recorrect 3-3-1-1 as 3-3-2-1 ;)
What should we do for excess 6?
Why do we need xs-3 code and where is it used?
we are not suppose to change the digit greater than 9 in xs 3 ??
What is meaning of unweighted code?
1) 01001001
2) 01101100
3) 0100010100111011
4) 5-2-1-1 is a self complementing code
3-3-1-1 is not self complimanting at 10:45...right it sir
That is 3321
Awesome teaching method, thank u sir
What is the purpose of self complementing codes?
1.01001001
2.01101100
3.0100010100111011
4. Self compliment code
How do you add the excess-3 to an octal?
HW-Solutions:
i)0100 0111
ii)0110 1100
iii)0100 0101 0011 1011
iv)5+2+1+1=9, Sum=9, hence self complementary.
Thanks for the video!
What is self complemented code??
how to check if a code is complementing or not if it is non-weighted(as their is no sum their)?
Sir what is the use and significane of self complementing code?
what is the decimal equivalent of XS-3 code of ( 1001 1000 1011).
you will have to add 0101 i.e 6 to the resulting BCD code to obtain it's decimal equivalent

Sir if u do xs3 for 658 the answer is 9 8 11 is this right .... Iam confused about the 11 part
Chandra Shekhar Chandu
We are not expressing it as 9 8 11...the XS-3 representation is 1100 1011 1011...We dont need to convert it to decimal... He did it that for checking purpose... If u go through the lecture once again,u will understand

Can we convert xs3 code into decimal. If so how?
Sir, I have one objection
The sum of
3-3-1-1 is equal to 8
But you told that it is equal to 9
It is not self complementing code
how is it un weighted code?
3311 is not self complimenting code.
24 decimal number is wrong 2 is 0010 is binary kk but xs - 3 is wrong 0011 is wrong
Sir how 3-3-1-1 is self complimenting??
3+3+1+1=8 which is ×= 9 .....then how sir??? Pls tell🙏🏻 I think it's a mistake
thank you for great lectures sir🙏🙏🙏.sir if possible please show your face.we want to know the great person behind this.

9 8 11
Why are you saying 8-4-2-1 Code is not Self-Complementing ? I think you might be wrong !
8-4-3-1=15 which is not equal to 9; thus its not an self complement bcause it should be 9 or less than 9;
aarthi vaishnavi I know it is not equal to 9 but yet it is self complement if you check it !
bro it is not self complement because 9 is a complement of 0
and if you check....0 =0000 and 9 = 1001.
hence they are not complement of each other
