This video is very informative, our textbook is pretty messed up when it comes to this part

Sir at 14:20 at case 4 is about if there is any error in extended bit ? Is it?

@ALLABOUTELECTRONICS 3 жыл бұрын

Yes, the case 4 is when there is an error in the extended bit.

at 13:42 , why having even Overall Parity equal and Check bits equal to '1' imply 2 errors?

@ALLABOUTELECTRONICS 4 ай бұрын

If there is a single error, then by checking the overall parity bit, you will know that there is an error. Because in case of single error, the overall parity of the code will be odd. But when there are two errors then overall parity will still be even. But checking the check bits, it is possible to detect where there is any error in the code or not. In case of two errors, the check bits won't be zero. So, it indicates that there is an error. And since the overall parity is even, it indicates there are two errors. (If the overall parity is odd, then it means that in odd number of bits of the code, there is an error ). I hope, it will clear your doubt.

@@ALLABOUTELECTRONICS thanks for your reply. After examining it further I realized the following : (a) If the overall parity is even AND the Hamming part is valid , the entire code word is valid . (b) If the overall parity is even AND the Hamming part is erroneous, then it has 2 errors , because it requires 2 bit flips to make the codeword valid (Otherwise , the overall parity would become odd due to single bit flip in the Hamming part). These 2 errors cannot be corrected, because Hamming decoding is limited to correcting only 1 erroneous bit. (c) If the overall parity is odd AND the Hamming part is valid , then the only error is in the parity bit, which can be corrected by flipping it. (d) If the overall parity is odd AND the Hamming part is erroneous, then there is a single error which is in the Hamming part (this bit is found via the check bits). correcting it will validate Both Hamming part and parity bit (because the erroneous bit is flipped).

13:52 U say like C1,c2,c3 will be non zero does it mean either C1,c2,c3 becomes non zero?
