EMD的程序要用到matlab的时频工具箱 matlab的工具箱的安装步骤： 1.解压下载的文件包，将tft/mfile复制到matlab的toolbox文件夹下 2.建立搜索路径，matlab->file->Set Path->Add Folder ->选择mfile文件夹复制到matlab的toolbox的路径->save->close 3.测试是否建立搜索路径成功，在matlab命令窗口打入：which fmsin 返回的结果是你放mfile的正确路径说明建立搜索路径成功。此时就完成了安装工具包的工作。(EMD program to use when the frequency of matlab toolbox matlab toolbox installation steps: Unzip the downloaded file package, copy tft/mfile to the toolbox matlab file folder 2 established the search path, matlab-> file-> Set Path-> Add Folder -> Select mfile folder to the toolbox matlab path-> save-> close 3 test whether to establish a successful search path in matlab command window enter: which fmsin The result returned is the correct path you put mfile instructions to establish a successful search path. This time to complete the installation kit work.)

1、不同阶次模拟巴特沃兹滤波器的频率响应 2、根据模拟滤波器指标，设计低通巴特沃兹滤波器 要求通带截止频率 fp = 5kHz, 通带最大衰减 ɑp =2dB， 阻带截止频率 fs= 12kHz, 阻 带最小衰减ɑs =30dB,按照上述指标设计巴特沃兹低通滤波器。 3、给定模拟滤波器，按照不同采样频率设计数字 IIR，观察采样频率对设计结果的影响 已知模拟滤波器传输函数 H(s)为 2 0.5012 ( ) 0.6449 0.7079 H s s s = + + 按照不同采样频率 Fs1=1Hz, Fs2=10Hz 使用脉冲响应不变法将 H(s)转换为 H(z)数字 IIR 滤波器。观察不同采样频率设计得到的数字 IIR 的差异。 4、给定数字 IIR 指标，用脉冲响应不变法设计 IIR。 数字低通滤波器的指标为: 0.2 , 1 , 0.3 , 15 p p s s ω π α ω π α = = = = dB dB ,使用巴特沃 兹滤波器设计数字 IIR。比较采样频率 Fs=1， 2 时设计过程中的模拟滤波器，数字滤波 器的变化。 5、用双线性变换法设计 IIR，并同脉冲响应不变法比较设计的结果。数字滤波器指标要 求如下 0.2 , 1 , 0.3 , 15 p p s s ω π α ω π α = = = = dB dB(1.Grasp the impulse response method and bilinear transformation design IIR filter principle and specific design methods, familiar with double A computer program for designing lowpass, bandpass and highpass IIR digital filters by linear design; 2 . familiar with the design of analog Butterworth filter, master impulse response method and bilinear transformation method to design digital IIR Filter method)
