rayleigh

一个十分简短却非常有用的产生组合数的程序。(A very brief but very useful for selecting the combination of several procedures.)

说明：  本程序是基于S变换的短时电能质量扰动检测方法实现的，用于分析电压暂降的幅值、相位跳变、持续时间和谐波含量进行分析(This procedure is based on the S transform short-term power quality disturbance detection method implemented for the analysis of voltage sag magnitude, phase transition, duration, and harmonic content analysis)

均匀PCM量化和u律非均匀量化的对比效果分析实验(uniform PCM quantifiable and non-uniform legal u quantitative analysis of the experimental contrast)

说明：  该方法自适应地将一个复杂的非平稳的多分量信号分解为若干个瞬时频率具有物理意义的乘积函数（Product function,简称PF）之和，其中每一个PF分量由一个包络信号和一个纯调频信号直接求出。包络信号就是该PF分量的瞬时幅值，而PF分量的瞬时频率则可以由纯调频信号直接求出，进一步将所有PF分量的瞬时幅值和瞬时频率组合，便可以得到原始信号的完整的时频分布。(This method adaptively decomposes a complex non-stationary multi-component signal into the sum of several product functions (PF) with physical meanings at instantaneous frequencies, where each PF component consists of an envelope signal and a pure The FM signal is directly obtained. The envelope signal is the instantaneous amplitude of the PF component, and the instantaneous frequency of the PF component can be directly obtained from the pure frequency modulation signal. Further, the instantaneous amplitude of all PF components and the instantaneous frequency are combined to obtain the complete original signal. Time-frequency distribution.)
