首先对设计中的模块进行初始化设置，之后通过声卡对数据进行采集并将采集的信号传输到LabVIEW模块中，通过LabVIEW模块的程序运行将信号转换成图像的形式显示出来，最后通过对波形的测试得到各种参数。(Firstly, in the design of module initialization, followed by the sound card on the data collection and acquisition of signals transmitted to the LabVIEW module, through the program LabVIEW module converts the signal into the form of image display, by the end of the waveform test to various parameters.)
