Consider the following set of codewords(Last bit is even parity of the first two bits)
Now here min. hamming distance is 2 and if i apply formulae
Min. hamming distance =d+1,then d errors can be detected
Means 1 error can be detected.
But in these set codewords if there is any 3 bit error,that will also be detected as parity will become odd.
So 3 bit error can also be detected,but by formula it says 1 bit error can be detected.
Please tell what did i miss?
