A single TD with retuning: (a) P(H) over time is controlled to stay around 0.5. (b) The dependency, or P(H) for n bits given an initial result of heads. (c) Counted streaks of 1’s (magenta points), compared to the expected number of streaks of exactly length N (black dashed line). (d) A temporal XOR of a single TD, computed by taking the XOR of pairs of sequential bits as they are produced and creating a new bitstream of half the length. (e) P(H) over time given an initial result of heads. Results are shown for a single TD as well as the TD after one, two, and three temporal XOR operations.
