【matlab编程代做】matlab信号分析的包络检测 ([Do] matlab matlab programming on behalf of the envelope detection signal analysis and system-level simulation of the road)

converter is suppressed according to CISPR 22 standard limits. The fundamental frequency component with higher order harmonics of 2 MHz resonant converter after the application of filter is at 33.18 dBµ V. The designed filter has attenuated the common mode conducted noise by 140 dBµ V.

说明：  利用遗传算法，对一个函数求取极值的一种方法，考虑到普通遗传算法中初始种群，对极值影响较大，程序的采用了多个初试种群同时学习，相互比较以求取极大值。(use of genetic algorithm, a function of a strike extreme methods, taking into account the general genetic algorithm initial population, Extreme right big impact and the procedures used to try various species while learning, in order to obtain comparable value.)

说明：  pca特征向量提取 利用pca的方法获取特征植及特征向量 最后可以自己根据需要降维(pca pca feature vector extraction method using characteristics of plants and to obtain the final feature vector dimension reduction can be their own as needed)
