说明：  经验模态分解（Empirical Mode Decomposition，简称EMD))方法被认为是2000年来以傅立叶变换为基础的线性和稳态频谱分析的一个重大突破，该方法是依据数据自身的时间尺度特征来进行信号分解，无须预先设定任何基函数。这一点与建立在先验性的谐波基函数和小波基函数上的傅里叶分解与小波分解方法具有本质性的差别。(Empirical mode decomposition (EMD) method is considered as a major breakthrough in linear and steady-state spectrum analysis based on Fourier transform since 2000. This method decomposes signals according to the time scale characteristics of the data itself, without setting any basis function in advance. This is essentially different from Fourier decomposition and wavelet decomposition based on prior harmonic basis function and wavelet basis function.)

说明：  DSP本身在内的所有电子器件都是干扰源，而且系统所处的工作环境中还有很多外来干扰源，再加上语音识别技术对信号噪声非常敏感，所以在系统设计中必须考虑系统的抗干扰问题。(DSP itself, including all electronic devices are sources of interference, and the system environment in which there are many external sources of interference, coupled with voice recognition technology is very sensitive to signal noise, so the system design must consider the system of anti- interference problem.)

频率步进信号在雷达成像等需要大带宽的场景十分有用，该文件为国外经典文献，值得参考(Stepped frequency radar imaging signal in scenes that require large bandwidth is useful, the document for foreign classic literature, it is also useful)

说明：  能够实现电力系统信号得EEMD分解，可用于电力系统低频振荡信号分解(It can realize EEMD decomposition of power system signals and can be used for power system low frequency oscillation signal decomposition)
