| 摘 要： | 生物电信号由于其发生机理和所处的生物体的电特性比较复杂、多变，故在处理这样的信号时，常规方法和电路往往难以实现不失真地撷取、放大和精确定量。介绍了一种生物电信号峰值测量方法，详细阐述了依据该方法设计的实用电路的结构、测试结果、误差分析及改进措施，并指出该测量方法具有构思巧妙，原理简单，易实现等优点，适用于大部分需要测量生物电信号峰值的系统中。

| Abstract: | It is always very difficult to process the bioelctrical signals, sampling, amplifying and quantifying because of the different sources it comes from and the mechanism it depends on. This paper mainly introduces a method of measuring the peak value of bioelectrical signals, expatiates on the structure, testing result, analysis for error and measure taken for improvement of the circuit designed by this method. At last, the paper also points out that the method is wonderful, simple, easy to carry out, and can be used in many medical systems. |
