该程序基于labview2012研发，利用希尔伯特变换实现提取信号的包络。一部分是对AM信号的仿真实验，另一部分是其通用形式，只需拷贝到自己的引用程序中即可。-The program is based on the labview2012 , the use of the Hilbert transform to extract the signal envelope. Part of the AM signal simulation, another part is in its generic form, can be simply copied to the reference program.
