心电、脉搏信号的提取和处理，心电脉搏特征波提取(Extraction and Processing of ECG and Pulse Signal and Extraction of ECG Pulse Characteristic Wave)

对脉搏信号进行滤波处理后，再进行时域分析和频域分析，提取出脉搏信号的周期、峰值、频率等特征。(After filtering the pulse signal, time domain analysis and frequency domain analysis are carried out to extract the characteristics of pulse signal such as period, peak value and frequency.)
