Next: Discussion Up: NOISETRAPS, AND SNAGS Previous: Circuits


Two experimental pictures are shown. First, we show an experimental picture (Figure 4) showing trapping and releasing of the state space variable in a real electronic system built to display these phenomena. In this experimentthe noise is ejecting the system from a fixed point trap; the Feature in this case is a trap.

And second, we show the corresponding experimental picture (Figure 5) showing the system entering and leaving a snag. The Feature is a snag but it is not apparent from this picture whether the noise is ejecting the system from the Feature, or whether the Feature is displaying crisis-induced intermittency.

At the conference presentation, a tape will be played demonstrating the sounds produced by these systems.
