| 摘 要： | 传统的信号发生器具有价格昂贵、携带不便、不易二次开发及维护性差等缺点。本文设计一种基于LabVIEW的多功能虚拟信号发生器,可以产生基本信号（正弦波、方波、三角波、锯齿波）和任意波形的信号,并具有对信号进行综合处理的功能,如滤波、将波形信号写入文件进行存储,也可以将信号经DAQ数据采集卡输出。

| Abstract: | The traditional signal generator has many shortcomings, such as high price, carry bulky, hardly maintained and so on. In this paper, a multi-function virtual signal generator is designed based on LabVIEW. By the new generator basic signals （sine wave, square wave, triangle wave, saw tooth wave） and random waveform signal can be generated, and signal processing function can be realized. For example, filter function, and also the waveform signals can be save into files or exported through the data acquisition card （DAQ）. |
