MATLAB实现锁相环，对初学者很有帮助(MATLAB to achieve phase-locked loop, very helpful for beginners)

自己编写的一个大批量不同类别数据录入程序，并且为防止因为数据量太大导致程序运行缓慢，将其改写成分批小规模数据。方便了大规模数据处理慢带来的各种不变。(I have written a large quantities of different types of data entry procedures, and because the amount of data in order to prevent too much causes the program to run slowly, be rewritten into small batches of data. Facilitate the large-scale data processing slow and the various unchanged.)

預失真是一種用於改善無線電發射機放大器線性度的技術。大多數電信系統中的無線電發射機放大器需要是“線性的”，因為它們必須準確地再現其輸入端存在的信號。 壓縮其輸入或具有非線性輸入/輸出關係的放大器導致輸出信號濺到相鄰的射頻上。 這會對其他無線電信道造成乾擾。(Predistortion is a technique used to improve the linearity of radio transmitter amplifiers. Radio transmitter amplifiers in most telecommunications systems are required to be "linear", in that they must accurately reproduce the signal present at their input. An amplifier that compresses its input or has a non-linear input/output relationship causes the output signal to splatter onto adjacent radio frequencies. This causes interference on other radio channels.)

说明：  对心音信号进行BT功率谱估计及切比雪夫1滤波的matlab程序，可粗略提取心音频率(PSD BT chey1 matlab)

主成分分析并用散点图分析前三个主成分M代码，请指教。(Principal component analysis and scatter analysis of the first three principal components M code, please advice.)

自己做的感应电机无速度传感器直接转矩控制仿真模型，特拿来分享，还望大家多多指教。(sensorless direct torque control for induction motor)

说明：  直接转矩控制的研究，它是基于MATLAB7.01的(Direct Torque Control of the research, which is based on the MATLAB7.01)
