Best answer 9 votes 9 votes $n$ is data bit $k$ is number of parity bits $n+k \leq 2^k-1$ , as parity bits are used at the locations in power of $2's$ . $n \leq 2^k-k-1$ $n= 16 $ $16\leq 2^k-k-1$ $k=5 $ Praveen Saini answered Apr 19, 2016 selected Apr 19, 2016 by Digvijay Pandey Praveen Saini comment Share Follow See all 3 Comments See all 3 3 Comments reply Shumile commented May 20, 2018 reply Follow Share Is it correct approach to finding parity bits?
