自适应陷波滤波器对地震信号中的50Hz工频干扰的消除。(Adaptive notch filter to seismic signal in the 50Hz interference elimination)

CONTROL OF DC MOTOR USING BUCK BOOST CONVERTER

说明：  LSB实现图像水印的嵌入与提取。真彩色图像为载体也可以！(LSB implements image watermarking embedding and extraction. True color images can also be used as carriers!)

说明：  地统计学中基于空间变异原理的差值分析，做空间分析的好材料。matlab实现(To statistical theory based on spatial variability of the difference analysis, a good material to do spatial analysis. matlab implementation)

利用幂法和反幂法求解按模最小特征值，按模最大特征值。与MATLAB中eig功能相似 (get the character value of a matrix, similiar with the function eig in matlab)

it includes some usefull codes in speech processing

this program do qam modulation and upsampling and downsampling and use raised cosine filteroj

这是一个使用希尔伯特黄变化提取心音包络的程序(extract the envelope of the heart sound based on hilbert-hung transfrom)

使用matlab仿真OFDM。其中描述了OFDM的基本原理，含详细的公式推导过程。在文章最后附有matlab代码，并且有仿真结果可参考。(Matlab simulation using OFDM. Describes one of the basic principles of OFDM, with a detailed formula derivation process. At the last article with matlab code, and have the simulation results can be found.)
