在LabVIEW上进行编程，使用滤波器组对其进行消噪，得到理想信号(The program is programmed on LabVIEW, and the filter is used to de-noising the signal and get the ideal signal.)

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.)

多个串口通信VI通过开关量实现交互，每次保证一个VI在运行
