脉搏信号采集的硬件实现结果图。用示波器显示。-Pulse signal acquisition hardware implementation result diagram. With an oscilloscope display.

使用阈值法对脉搏信号的峰值进行提取，并且通过提取信号的峰值求脉搏信号的周期，并且简单判断脉搏信号的峰值是否可用。-Useing Threshold to extrack the peak of the pulse signal extraction, and determine the peak of the pulse signal whether is not available.
