In 1995, Thomas Carroll designed an easy-to-build electronic circuit for producing chaotic behaviors. He started from the Rössler equations  where he replaced the nonlinear term by a piecewise linear function , leading to the system
where the nonlinearity is the piecewise linear function
The electronic circuit corresponding to these equations is shown in Fig. 1. The three variables correspond to three voltages measured in the circuit as indicated in Fig. 1.
Using parameter values as used in , that is, as
