Question

For 8 information bits, what is the minimum number of parity bits that must be added in hamming code for single error correction

Answer 1

$formulae \: we \: used \: for \: finding \: \\ hamming \: code \: problem \: is \\ m + r + 1 < = 2^{r} \\ where \: m \: is \: information \: bits \\ r \: is \: parity \: bits \: to \: be \: added \\ so \: 8 + 1 + r = 2 {}^{r} \\ r = 4$
