Ratched cellular automata Movies
Ratchet cellular automata allow to build up a complete logic architecture to per-form logical operations comprising dif-ferent gates. Here we demonstrate ope-ration of a fan-out gate where identical information is copied simultaneously to two ends.
With the proposed scheme one can also realize transmission lines where in-formation (here encoded as defects) can be propagated in a well defined direction. The example shows how a defect is introduced from the left and propagates to the right under the influence of the externally applied clocking algorithm.
