This provided the impetus for researchers to develop the error detection and correction codes discussed here. Without FEC the world would be quite different.

This Golay code implementation is capable of correcting three-bit errors in each 24-bit block, with 12 bits available for payload. That’s what the numbers in those brackets mean.

Given three-bit corrections, for example, one could elect to use two of those bits for repairing errors and one bit for run-time reading noise. This creates some room for push and pull between the ...
