Generate_Sound
- 将心电数据从文件中读取出来,并由声卡读入,从而发出心跳声,可将得到的声音作为模拟的心电信号-ECG data will be read out from the file, read by the sound card, which issued a heartbeat sound, the sound can be simulated ECG signal as
filters-used-to-heart-noise
- 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
