听觉实验研究的微计算机系统

本文叙述应用于听觉研究的微计算机系统.该系统包括:多种波形发生器、专用键盘、显示屏、接口和4个微计算机芯片8085等.外围有xy记录仪、示波器、照相机等.系统能产生参数可编程序的复杂声音;处理实验动物生物电脉冲;能按获得的结果自动改变实验的步骤;在xy记录仪上以直方图形式画出实验结果.系统具有多个常用实验程序,操作简易.在其EPROM中有许多子程序可供调用,用户能按自己的意图方便地编写新的程序.设计中采用数字和模拟电路相结合,使系统能以很少的硬件和资金获得合宜的性能.

A Microcomputer System for Auditory Research

Microcomputer system consists of a newly designed mainframe (including 4 microcomputer chips 8085, 8155, 8185 and 8755, a multiwaveform generator, a special keyboard, a display panel and interfaces) and peripherals (including a XY plotter, anoscilloscope, a camera etc.). The system can generate the complex stimulating soundwith programmable parameters, process the bioelectric pulses recorded from the experimental animal, change the way of experimental observation according to the resultsobtained, transfer the data of results to XY plotter and plot in the form of histogram.A series of programs for routine experiments are available and easy to use. In addition,there are also a variety of subroutines in the EPROM. It is possible and convenient tomake new programs according to user's intention. By combining digital and analoguecircuits the system can be built with little hardware resources and investment and havereasonable performance.
