加信噪声，单边带调幅，设计波特滤波器，过滤噪声，比较经过希尔伯特变换前后的区别-Plus letter noise, single-sideband amplitude modulation design Potter filters, filter noise comparison, after the difference between before and after the Hilbert transform

希尔伯特黄变换，源码由台湾中央大学进行编写开发，在此特别说明。

很详细的hht编程代码，matlab亲测可用，提供了比较清晰的注释，帮助理解(Very detailed HHT programming code, matlab pro test available, provides a relatively clear note to help understand)

希尔伯特-黄变换的matlab程序，内含集合经验模态分解文件(Hilbert Huang transform matlab program, including set empirical mode decomposition file)
