It's purpose is to remove bias: the propensity of physical random processes to produce more 1s than 0s (or v.v.). Unlike some whiteners (AES?) it can be implemented with a handful of gates.
- rrauenza 5y agoYes, that's it. And it's used to eliminate bias. I found a good explanation at https://www.youtube.com/watch?v=xquB4rDbsvc https://www.youtube.com/watch?v=xquB4rDbsvc at about 14min.
