Question

I am asked to submit the 21-digit string as my answer. Without any spaces or X oe Y in the string. can you tell me that?

Expert Solution
Step 1

When spreading out the string 1111100011101100 to include parity bits, we first need to determine the number of parity bits required to cover the string.

To determine the number of parity bits, we can use the formula 2^r ≥ m + r + 1, where r is the number of parity bits and m is the number of data bits.

In this case, m = 16, so we need to find the smallest value of r that satisfies 2^r ≥ 16 + r + 1.

Trying different values of r, we find that r = 5 satisfies the condition, as 2^5 = 32 ≥ 22 = 16 + 5 + 1. Therefore, we need 5 parity bits to cover the string.
