Best answer 12 12 votes Code is 1110 0100 1111 Now check Parity bit P1=$1\oplus 0\oplus 1\oplus 0\oplus 1\oplus 1=0$ P2=$1\oplus 1\oplus 1\oplus 0\oplus 1\oplus 1=1$ P4=$0\oplus 0\oplus 1\oplus 0\oplus 1=0$ P8=$0\oplus 1\oplus 1\oplus 1\oplus 1=0$ So, Error in 2nd bit original bit is 1010 0100 1111 =A4F srestha answered Sep 14, 2016 • selected Sep 14, 2016 by dd srestha comment Share Follow See all 9 Comments 9 9 Comments reply Sushant Gokhale commented Sep 29, 2016 reply Follow flag @Sreshtha, I know hamming (7,4) where 4 are data bits and 3 generator bits.
