摘要
从信号采集与处理的基本原理和技术出发,结合计算机编程技术,实现了利用软件模拟硬件的功能.系统软件采用C语言编写,具有数据采集、数字示波、波形记录、数据分析、数据滤波处理、数据输出、标准波形发生、任意波形发生及图形打印等功能。
Based on the foundmental theory and technology of signal gethering and processing,combining computer programing and indicated interface cards, a multi functional compute systen is established. The system can be viewed as a virtual instrument which has the functions of signal processing and functions of signal generater. As a signal processor, the system can perform signal fikering, programed data analysis, signal gethering and display; as a signal generator, the system can generate signals with different types, frequencies, phases and megnitudes.
