In a block code a dataword is 20 bits the corresponding code

In a block code, a dataword is 20 bits, the corresponding codeword is 25 bits. What are the values of k, r, n according to the definition in the textbook? How many redundant bits are added to each dataword?

Solution

Given that,

data word, K = 20 bits

code word, N = 25 bits

Redundant bits R = N - K

= 25 - 20

= 5 bits
