Question

What is hamming distance code for detecting?

• A. d
• B. d+1
• C. d+2
• D. 2d+1

Answer 1

The correct option is B d+1

Hamming distance code for detecting is d+1.

Hamming code is a set of error-correction code s that can be used to detect and correct bit errors that can occur when computer data is moved or stored.

If two code words are Hamming distance d apart, it will take done-bit errors to convert one into the other. To detect (but not correct) up to d errors per length n, you need a coding scheme where code words are at least (d+1) apart in Hamming distance.
