IIR
用双线性变换法设计IIR数字滤波器
(1)用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为:在通
带内频率低于0.2π 时,最大衰减小于1dB;在阻带内[0.3π ,π ] 频率区间上,最小衰减大于15dB。
(2)以0.02π 为采样间隔,打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性
曲线。
(3)用所设计的滤波器对实际心电图信号采样序列(在本实验后面给出)进行仿真滤
波处理,并分别打印出滤波前后的心电图信号波形图,观察总结滤波作用与效果。

guess
需要一个放有若干图片的文件夹,图片的文件名还需要提供一些信息,如“计61班.jpg”之类,具体格式可以修改源代码。然后显示图片让参与者猜是哪个班的。为系里男生节编写的一个简单的GUI程序(Need a put several pictures folder, pictures of the file name also need to provide some information, such as "(61 class. JPG," and so on, and the specific format can make changes to the source code. And then display picture participants had to guess which class is. For the day of a boy to write simple GUI program)
