MCQ Practice Question

A standard Hamming code with minimum Hamming distance dmin=3 can?

ACorrect one bit error but not guarantee correction of two bit errors
BCorrect any two bit errors
CCorrect any three bit errors
DOnly detect one bit error and correct none

Correct Answer: A. Correct one bit error but not guarantee correction of two bit errors

Explanation: A code with dmin=3 can correct floor((dmin−1)/2)=1 error. It can detect up to two errors, but ordinary Hamming decoding cannot reliably correct two.
