The electronic analog of the bouncing ball is developed as a simple classroom experiment illustrating all the important features of this nonlinear chaotic system. In an operational amplifier circuit conventionally used to simulate the free fall of a ball in constant gravity, current feedback through a precision diode rectifier is used to model free fall when the rectifier is backward biased, and the bounce when the rectifier is conducting. The ease with which parameters are controlled and variables measured permits the investigation in great detail of the specific dynamic behavior of the bouncing ball.
