3) is the study of the range where the oscillations of the individual state variables are confined. To this aim, the model is simulated with MATLAB . The trend of the three-state variables x, y, and z and the corresponding attractor are shown in Figs. 2. 1 The Jerk Circuit 35 Fig. 3). Components: D = 1N4148 Diode, R1 = 1 kπ, R2 = 1 kπ, R3 = 1 kπ, R4 = 1 kπ, R5 = 1 kπ, R6 = 1 kπ, C1 = 1 µF, C2 = 1 µF, C3 = 1 µF, Operational Amplifier = TL084, Vcc = 9 V As it can be noticed, all the three variables oscillate in a range which is compatible with a voltage power supply fixed to ±9 V, so the variables do not need to be scaled.

10), we derive the circuit scheme of Fig. 20. Off-the-shelf resistors and capacitors, each with its own tolerance, are chosen as reported in the caption of Fig. 20. The choice of C1 and R6 fixes the time rescaling as κ = R61C1 = 10000. The circuit obeys the equation: R5 R5 R5 X− Y− Z. 3 An Example: The Rössler System 27 Fig. 21 Scheme of the circuit associated to the second rescaled Rössler equation. Parameters are: R8 = 78 kβ, R9 = 100 kβ, R10 = 78 kβ, R11 = 100 kβ, R12 = 1 kβ, C2 = 100 nF, Vcc = 9 V In a similar way, we proceed for the other two state variables.

36, the behavior of x, y, z, and w exhibits the typical features of a chaotic signal. Despite the waveforms of the state variables x, y, z, and w have acceptable operating ranges, feasibility problems, due to the mathematical operations involving them and leading to terms over the voltage supply bounds as evidenced by simulations with the electronic circuit simulator PSPICE appear. Thus, the variables of the circuit (in particular, x and w) are scaled with the scaling factors listed below: X = k1 x; where k1 = 1 ; 5 Y = k2 y; k2 = 1; Z = k3 z; k3 = 1; W = k4 w k4 = 2.
