Here addition is xor addition or mod2 addition, so you don't need to consider carry in addition

[mayankprajapati]

Sir I'm confuced in 2nd and 3rd property.
You just speak condition and you don't explain it properly.
Ex. In 3rd property how does Dmin and Wmin calculated.
Plz give proper explanation.

[vintibhatia]

sir in example (4, 3) even parity code if we take c3 and c4 as it is resulting in c7, but then 2nd property is not satisfying. why?

[aasthabisaria]

Sir please explain how did you code the c10 etc

[PrashantSingh-blms]

sir in which video have you explained (7, 4) hamming code C1, C10 & C11

[shwetajain]

value of c10 is not correct so dont worry about it if you are not getting the cocept correctly. it should be 1010010

[utkarshgaikwad]

Property 2 and 3 not explained properly. No explanation on what is hamming distance and weight

[revanthsaiesh]

Sir How did you write the code 1010011 as

[ra_nyk]

C11 is invalid code right it has error

[aishwaryasrivastava]

the addition of c1 and c 10 is wrong 1+1 is 10 means 0 and 1 will carry so other will be 1 +1+1 which will be equal to 1 carry 1 addition is perform from right to left not left to right .... how you have done that addition at 3:10 plzz check

[VikashKumar-ugjx]

sir if we take c3 and c7 then in case of even parity .it not satisfied d(i, k)=d(cp)

[mohamedlagad]

unlike other session this may need more basic explanation i watched all the way here and i'm appretiate your good explanation

[samyaktjain]

sir, please try to explain clearly and each basic point.

[marwanashraf]

Addition of two binary numbers is done from right to left

[mayankdungarwal]

sir if we take c11 without parity bits then it is c10 ..how?

[sabamansoori]

An (8, 4) linear block code is constructed by shortening a (15, 11) Humming code generated by the generator polynomial g(P) P+P+1

(i) Construct the code words of the (8, 4) code and list them

(ii) What is the minimum distance of (8, 4) code pls give solution of this numerical

[saivyshnavi]

may i know .... which text book you are following

[jagadeesh]

wonderful explanation i have even seen <3
