I really wished to have a teacher like you in my university but found it on youtube. I really appreciate your efforts in making us all understand each and every concept in such an easiest manner as well as in a short period of time. Thankss a lot Sir. You can't even imagine how precious your videos are for us.

in this example minimum hamming distance is not 2, it 1 if you are not taking parity bit during xor and it is 3 if you are taking parity bit during xor. one more thing it can detect all odd bit errors, as you said earlier, not only d-1 bit error

[@livegamer6698]

its 2 if taking parity bit

Hamming distance = Perform XOR operation and then count no of 1's obtained in the answer.

[@sonybharti8797]

minimum hamming distance shoud be 1 for your given code word, when we perform xor operation for 0000 and 0001.

[@yasharora4114]

actually we perform xor operation of valid words which are formed when parity bit is included so acc to your given situation it will be 0000 to 00000 and 0001 to 00011 so as you can see now it will give haming distance of 2. Hope this will clear your doubt.

[@guptahemanshi]

@@yasharora4114 XOR operation between 00000 and 00011 will give 00011. Converting this in decimal format, it will be 3 and not 2. Can you please suggest where I may be going wrong ? Thanks.

[@guptahemanshi]

Sorry. I figured my mistake. Hamming distance is the number of 1s in the data received after XOR operation. We do not have to convert it to decimal. Thanks though.

[@deemeekshya5986]

@@yasharora4114 thank you for explanation, he had not included parity bit while performing hamming distance between 0101 1 ad 1000 1 which would give value of 4 instead of 3, hence in other way there is a small error.

sir you said that min hamming dis is 2 for these nos , but when ex or of 0001 and 0011 is 0010 means hamming distance is 1 , min hamming distance is 1. please correct me if i am wrong.. you only took the bits without the parity bit so should we take the parity bits while counting the hamming distance or not please give solution.

sir, what if the parity changes during sending the data from sender to receiver in single parity

[@vishrockzz444]

same doubt

[@014_ramyaneelakantan7]

Same doubt

[@rakshdeep5742]

As explained, this method can only check for changes in odd number of bits. So, as an example for even parity: Lets take 0001 1 with the last bit denoting the parity bit. In this case if we change the parity bit to 0, then we get 0001 0 But the data word 0001 0 is itself not correct according to even parity check as it has odd number of ones.

[@nirajvaghasiya669]

Sir in this video minimum hamming distance= 1 is 1110 and 1111 so how we can says minimum hamming distance is = 2

[@tirthsuthar6754]

niraj we have to considered the last parity bit also so after parity bit the data will be something like this : 11101 XOR 11110 and hence now d=2... sir is this correct?

[@thewanderer9603]

Sir the hamming distance of 0010 and 1010 is 1 but as you have mentioned in the video that minimum hamming distance is 2 so m getting a doubt can you plzz explain it
