脉搏波所呈现出来的形态、强度、速率和节律等方面的综合信息，能反映出人体心血管系统中许多生理疾病的血流特征。根据人体脉搏信号特征，本文设计了一种脉搏波动频率测量系统。-Comprehensive information presented pulse wave form, strength, speed and rhythm, etc., can reflect the human cardiovascular system, the blood flow of many physiological disorders. According to human pulse signal characteristics, design a pulse fluctuation frequency measurement system.
