用kalman算法实现系统辨识，最终实现滤波，具有精度高，收敛快的特点(System identification algorithm using kalman, and ultimately the filter, with high precision, fast convergence characteristics)

利用双线性Z变换设计巴特沃斯和切比雪夫I型IIR数字滤波器，包括低通、高通、带通、带阻四种形式。使用者只需指定通带、阻带的边缘实际频率及相应的衰减，便可输出数字滤波器 的级联形式的各子系统分子、分母的系数，并输出其幅频和相频响(Bilinear Z transform design Butterworth and Chebyshev Type I IIR digital filters, including low pass, high pass, band pass, band stop four forms. Users simply specify the passband edge frequency stopband actual and corresponding attenuation subsystems can form molecular cascade output digital filter coefficients of the denominator, and the output of its magnitude and phase frequency response)

利用MATLAB产生三角波的模型， 功放模型仿真中的三角载波，经过测试，数据还是比较准确的(Using MATLAB to produce triangle wave model)

首先介绍计算机仿真技术和仿真建模方法的基本概念，以 便对建模和仿真有个初步和整体的认识；然后对 Simulink 进 行简单介绍，并以一个简单例子进行引导；最后介绍 Simulink 的工作原理，为后续的深入掌握 Simulink 打下基础(First introduced the computer simulation technology and the basic concepts of simulation modeling methods, modeling and simulation in order to have a preliminary and general awareness then Simulink for a brief introduction, and to boot a simple example Finally Simulink works, Simulink for subsequent understanding of the foundation)
