设计一个8阶以内的带通滤波器，通带截止频率fc1=30070HZ，fc2=32170HZ，通带内允许最大衰减0.2dB。设计满足要求的Butterworth滤波器和chebyshev滤波器。以RC运放为基本单元以最易实现的原则完成电路设计及参数选择，并根据设计参数进行幅频特性和相频特性的仿真，给出仿真曲线。分析电路的无源灵敏度。(Design within an 8-order band-pass filter, the passband cutoff frequencies FC1 = 30070HZ, FC2 = 32170HZ allow maximum attenuation 0.2dB within the passband. Designed to meet the requirements of the Butterworth filter and chebyshev filter. RC op amp is the basic unit is the most easy to implement the principle of complete circuit design and parameter selection, and in accordance with the design parameters of the amplitude-frequency characteristics and phase-frequency characteristics of the simulation, simulation curve. Passive sensitivity of the analysis circuit.)

说明：  关于圆盘耦合摆的研究，将介绍单圆盘耦合发电机模型和双圆盘耦合发电机模型的非线性方程组。通过对方程组的分析和MATLAB模拟计算，指出前者电流有稳定的周期解，后者在两圆盘角速度不同时可能进入混沌态，并且通过数值计算其Lyapunov指数（其中一个，出现了正值）来证明其混沌态(Research on the disk coupled pendulums, will introduce the model of a single disc and double disc coupling generator generator model coupled nonlinear equations. Equations through the analysis and MATLAB simulation, that the former current of a stable periodic solution, which is not the same in the two-disc angular velocity may enter the chaotic state, and by numerical calculation of its Lyapunov index (one of which, there have been positive) to prove the chaotic state)
