A chaotic attractor, known as "the double scroll" because of its shape in the (x, y, z) space, was first observed in a circuit containing a nonlinear element such that f(x) was a 3-segment piecewise-linear function.
En kaotisk attraktor, kendt som "The Double Scroll" pga. dens form i (x,y,z) rummet, blev først observeret i et kredsløb indeholdende et ikke-lineart element så at f(x) var et 3-segment stykkevis-linear funktion.
