弹跳球的电子模拟开发作为一个简单的课堂实验，说明了这个非线性混沌系统的所有重要特征。在通常用于模拟球在恒定重力下的自由落体的运算放大器电路中，通过精密二极管整流器的电流反馈用于在整流器被反向偏置时模拟自由落体，以及在整流器导通时模拟反弹。控制参数和测量变量的容易性允许对弹跳球的特定动态行为进行非常详细的研究。
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.
