为了把计算机技术引入本科生和研究生的实验教学,改革实验方法和手段,我们设计了“数据采集与处理系统”,现己用于实验教学,效果较好。现把该系统介绍如下。一、系统的主要功能与特性 1.可服务的实验组数:1~4组,2.被测电压值:≤±5 V(直流),3.模数转换分辨率:12位;4.采样频率:≥10000Hz;5.动态测试最大样本容量:6500点;6.每实验台(桌)可测信号线数:单线;7.可做回归分析、误差分析,可处理动态信号的最大
In order to introduce the computer technology into the experimental teaching of undergraduates and postgraduates and to reform the experimental methods and methods, we have designed a “data acquisition and processing system”, which is now used in experimental teaching and has achieved good results. Now introduce the system as follows. First, the system’s main functions and features 1 can serve the experimental groups: 1 to 4 groups, 2. The measured voltage value: ≤ ± 5 V (DC), 3. ADC resolution: 12; Sampling frequency: ≥10000Hz; 5. Dynamic test maximum sample size: 6500 points; 6. Each test bench (table) measurable signal lines: single line; 7. Can do regression analysis, error analysis, can handle the maximum dynamic signal
