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
Using parameter values as used in , that is, as
