The objective of this project is to develop a microcomputer-based system to monitor the electrical and chemical responses of nerve fiber individually and in combination. The system is capable of controlling eight nerve fiber samples simultaneously, and allows the researcher to: (i) study the effects of different stimulus amplitudes, and duration, (ii) provide real-time data processing, and (ii) store the collected data and display result in a tabular form and/or graphically. The system consists of two subsystems, the microcomputer and the analog subsystem. The microcomputer is a 80486-based microcomputer system. The analog subsystem consists of Instrumentation Amplifiers, Analog Multiplexer, Analog-to-Digital Converter, Digital-to-Analog Converter, and Sample-and-Hold with multiplexed input. In addition to the hardware, the software is being developed which consists of a main program and many other routines.
本项目的目标是开发一个基于微型计算机的系统，用于单独或组合监测神经纤维的电反应和化学反应。该系统能够同时控制八个神经纤维样本，并允许研究人员：（i）研究不同刺激幅度和持续时间的影响，（ii）进行实时数据处理，以及（iii）存储收集的数据并以表格形式和/或图形方式显示结果。该系统由两个子系统组成，即微型计算机和模拟子系统。微型计算机是基于80486的微型计算机系统。模拟子系统由仪表放大器、模拟多路复用器、模数转换器、数模转换器以及具有多路复用输入的采样保持器组成。除了硬件之外，正在开发的软件包括一个主程序和许多其他程序。
