一个按自己意愿设计子图和轴外注释的小程序，很具有个性化。(A small program to design figure and explanation of outer axes according to one s own willingness, with personal characteristics.)

灰色预测gm(1,1),gm(1,n)能有效快速解决灰色预测的处理问题。(gm(1,1),gm(1,n) can sole the problem of GM model easily)

结合具体应用，以2倍抽取为例，简要分析了多相滤波的基本原理及具体实现方法，并附带了matlab代码，从实验结果可以看出多相滤波可以实现与传统FIR滤波相同的功能。(Combine concrete application, take 200 extracts as an example, the synopsis analyzes the radical principle that the polyphase filters and concretely carries out a method, and supplementary matlab code, can discover polyphase to filter as a result to carry out to filter same function with traditional FIR from the experiment.)

说明：  Matlab地震波显示程序 Matlab的矩阵数据类型与地震波数据类似 (Matlab seismic display program Matlab matrix data types and seismic wave data similar)

需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序，或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换，甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)

用MATLAB程序实现了tcm_8psk的中频调制解调，有性能检测以及加入了非线性因素，很详细，毕设用的程序，比较实用。(Using MATLAB program implements tcm_8psk IF modulation and demodulation, a performance test and joined the non-linear factors, very detailed, complete set with the procedure more practical.)
