PLL锁相环的搭建，通过坐标变换实现锁相(PLL Phase-Locked Loop)

Statistics toolbox is necessary only to caculate t and F distributions for the number of samples at the specified alpha. These values could be obtained a table and manually inserted in the code, thus negating the use of the statistics toolbox.

Power line interference removal (50/60 Hz) from a recorded biomedical signals by a notch filter.

Tranformasi wavelet merupakan perbaikan dari transformasi Fourier. Transformasi Fourier hanya dapat menangkap informasi apakahsuatu sinyal memiliki frekuensi tertentu ataukah tidak, tapi tidak dapat menangkap dimana frekuensi itu terjadi. Jika Transformasi Fourier hanya memberikan informasi tentang frekuensisuatu sinyal, maka transformasi wavelet memberikan informasi tentang kombinasi skala dan frekuensi

归一化切割和图像分割算法及其论文,归一化分割不仅度量了不同分组之间总体不相似性，同时度量了分组内的总体相似性(Normalized cuts and image segmentation algorithm and its papers, normalized measure divided not only between the different groups no overall similarity, while the overall measure of similarity within groups)

说明：  混沌系统的相空间重构，可用于分析庞加莱截面(reconstruction of state space)

一本关于自适应滤波原理的习题答案，挺有用的(An adaptive filter on the principle of problem sets, winter ridge used)

自搭建-4相开关磁阻电机电流斩波控制仿真，有速度闭环。(Since the phase switched reluctance motor structures-4 current chopping control simulation, the speed loop.)

pusrsuing my doctorate in mechanical engineering at present doing in finite element methods
