该系统是基于声卡的多功能信号发生器的系统设计，主要是利用计算机的声卡实现波形的发生与输出，结合labview中的一些波形发生函数，在声卡上实现各种基本信号的发生和自定义信号的发生，并能把实时数据记录下来，实现历史数据的存储于回放。-This system is based on the sound card of the multifunctional signal generator system design, mainly is to use computer sound card to

基于labview的自定义波形发生器，能发出正弦波，三角波，方波，锯齿波等等波形。(Using Labview to design a virtual function signal generator, through the data acquisition card output waveform signal, adjust the relevant parameters of signal, to observe changes of the oscilloscope waveform
