读取心电数据,画出心电数据的波形和频谱图,观察心电数据的频率段范围
2.分别添加以下噪声(至少3种),画出噪声信号的频谱图,验证设计的噪声是否符合要求
(1)基线漂移
基线漂移通常为频率非常非常低的噪声信号,添加了基线漂移后的心电信号可以观察到原始信号整体的上下浮动
(2)高频噪声
高频噪声可以设计为大于100Hz的随机信号
(3)呼吸噪声
人体的呼吸带来的干扰大约在0.1Hz~0.25Hz
(4)50HZ工频信号干扰(必做)
50Hz工频信号的干扰较其他几种干扰的幅值稍大
3.画出加入噪声后的心电信号的波形图及频谱图,观察加入噪声后的心电信号及其频率范围
4.自己拟定参数设计各个滤波器,画出各种滤波器的冲激响应波形
五、用自己设计的滤波器,对加入了噪声后的心电信号进行滤波处理
