Ecc how many bits

How do we tell which? The three subsets of the data bits used to create the ECC bits in this example were chosen so that changing any single data bit produces a different ECC value than changing any other data bit.

If we assume the error is in Bit 7, we can change it and recalculate the ECC values as Since that doesn't match the received , we try Bit 5, which gives us , also not a match. This leaves Bit 3; changing its value gives us the correct ECC bits and confirms the correct data.
