How many Hamming bits are inserted into a 100 bit message?

To determine the number of Hamming bits needed for a 100-bit message, we can use the formula (2^r \geq m + r + 1), where (m) is the number of data bits (100 in this case) and (r) is the number of Hamming bits. Solving this inequality, we find that 7 Hamming bits are needed, as (2^7 = 128) satisfies (100 + 7 + 1 = 108). Thus, for a 100-bit message, 7 Hamming bits are inserted.
