这些是我到目前在PKU上做出的题目，给大家分享一下。-These are what I currently make in the PKU subject to share with you.

说明：  利用连续小波变换实现对地震信号的拓频 本程序可以实现对高频小波系数的提取、放大(Using continuous wavelet transform to expand the frequency of seismic signal)

说明：  微信小程序，简称小程序，英文名Mini Program，是一种不需要下载安装即可使用的应用，它实现了应用“触手可及”的梦想，用户扫一扫或搜一下即可打开应用。(Weixin applet, short for "applet", is an application that can be used without downloading and installing. It realizes the dream of "accessible" application. Users can open the application by sweeping or searching.)

用MATLAB仿真实现卡尔曼滤波器，仿真效果非常好。(MATLAB simulation Kalman filter, the simulation results is very good.)
