Homework Help: (15,11) Hamming Code, need help too work out how to calculate check digits

  1. Apr 12, 2012 #1
    1. The problem statement, all variables and given/known data
    I need to figure out how to find out the amount of check digits in a (15,11) hamming code. I know the amount of check digits is four and the amount of information digits is 7 but I don't know how to figure out how to get the answer, I only have the answer.
    2. Relevant equations
    I was given the equation n=4+c
    n=2^c - 1
    3. The attempt at a solution
    I do not understand how the equation above is possible, so i could not figure out how the result c=2^c-5 was achieved

    Normally a (15,11) hamming code would mean 15 total bits, 11 of which are data.
