labview用的基于声卡的虚拟示波器的程序。(LabVIEW uses a sound card based virtual oscilloscope program.)

基于声卡的虚拟仪器示波器，通过声卡进行数据采集，再由LABview显示波形。(A virtual instrument oscilloscope based on sound card is used to collect data through a sound card, and then the waveform is displayed by LABview.)

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

用LabVIEW做的一个简单示波器程序，把噪声信号和正弦信号混合后的波形进行滤波(A simple oscilloscope program made by LabVIEW filters the mixed waveform of noise signal and sinusoidal signal.)
