精密神经阈值刺激仪系统软件的开发

The Software Development for Precision Neuron-threshold Stimulator

人体电生理信号由于其频率低、信号弱等特性,对其放大、测量有其它信号所不可比拟的特殊要求。主要介绍了精密神经阈值刺激仪系统软件编写的原理和编写方法,针对仪器对系统软件的较高要求,如实时性,计算、测量速度和精度,以及对生物低频弱信号放大、处理控制等,着重阐述了系统软件设计所采用的处理结构和设计原则、注重点。

It has more unusual request to amplify and measure bioelectrical signal for its characteristic of low frequency and faintness. This paper mainly introduces the theory and designing method of the software for precision neuronthreshold stimulator, and emphasizes the designing principle and the structure of software for its high require in realtime and accuracy.
