Single Bit Error Correction & Double Bit Error Detection
Can someone explain, in their own words, what Double Bit Error Detection is and how to derive it? An example of corrupted data and how to detect the double bit would be appreciated.
I can do Single Bit Error Correction using parity bits as well as correct the flipped bit. Now when I reach Double Bit Error Detection I understand there is an extra DED bit, which is somehow related to the even or odd parity of the bit sequence. However, I am lost.
