Using a Chua's circuit, this shape is viewed on an oscilloscope using the X, Y, and Z output signals of the circuit. This chaotic attractor is known as the double scroll because of its shape in three-dimensional space, which is similar to two saturn-like rings connected by swirling lines.

Numerical analysis of the double-scroll attractor has shown that its geometrical structure is made up of an infinite number of fractal-like layers. Each cross section appears to be a

The double-scroll system is often described by a system of three nonlinear ordinary differential equations and a 3-segment piecewise-linear equation (see 2806: 2842: 2782: 2818: 3556: 3316: 2578: 3509: 3456: 3789: 3831: 3519: 1459: 4024: 214: 3706: 878: 2503: 2154: 562: 1089: 74:). This makes the system easily simulated numerically and easily manifested physically due to Chua's circuits' simple design. 3524: 3514: 449: 3779: 1219: 3871: 3644: 1296: 994: 675: 336: 789: 1856:
