matlab时频分析工具箱，里面涵盖了大多数能用到的相关函数程序。(matlab time-frequence analysis tools box.)

说明：  本课题基于MATLAB平台的数字信号处理仿真演示系统。数字信号即离散信号，本设计带有一个丰富得GUI人机交互界面，一共包括4个部分，分别为：离散时间信号的卷积，基本函数的Z变换（单位阶跃信号，脉冲信号，斜变信号，正余弦信号，指数系列信号），Z变换的基本性质（线性，位移，z域尺度变换，时域卷积），傅里叶变换的基本性质。是一个不错的选题，GUI设计逻辑清晰，章节清晰，层次明了。(This project is based on MATLAB platform of digital signal processing simulation demonstration system. Digital signal is discrete signal. This design has a rich GUI human-computer interface, including four parts: convolution of discrete-time signal, Z-transform of basic function (unit step signal, pulse signal, oblique signal, sine cosine signal, exponential series signal), basic properties of Z-transform (linear, displacement, z-domain scale transformation, time-domain convolution), The basic properties of Fourier transform. GUI design logic is clear, chapter is clear, level is clear.)
