Abstract An experimental model of a Duffing oscillator is presented. It consists of a linear inductance, a resistance and a ferroelectric nonlinear capacitance. A computer controlled measuring system recorded quantitatively the phase portrait of this series-resonance circuit. The comparison of experimentally observed phase portraits with those calculated by a computer allows to check different assumptions about the nature of the nonlinear properties
