多频道功率谱计算程序，比常规功率分辨率更高(Multi-channel power spectrum calculation program, a higher resolution than conventional power)

离散傅立叶变换已成为数字信号处理的重要工具，然而，它的计算量较大，运算时间长，在某种程度上却限制了它的使用范围。快速算法大大提高了运算速度，在某些应用场合已能作到实时处理，并且开始应用于控制系统。(Discrete Fourier Transform digital signal processing has become an important tool, however, the calculation of its larger, long computing time, but in a way limits the scope of its use. Fast Algorithm for greatly enhanced speed of operation, in some applications has been able to do real-time processing and control system began to be used.)

HHT是历史上首次对Fourier变换的基本信号和频率定义作的创造性的改进。他们不再认为组成信号的基本信号是正弦信号,而是一种称为固有模态函数的信号(HHT is the first time in the history of the Fourier transform basic definition signals and frequencies for creative change Progressive. They will no longer signal that the basic component signal is sinusoidal signal, but as an intrinsic mode function signals)
