Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.

偶编写的倒立摆系统的MATlab关于模糊自适应控制的对象和控制器S函数，以及Simulink模块文件，一个完全实现的倒立摆程序，发表文章很有用(Even the preparation of the inverted pendulum system on the Matlab fuzzy adaptive control of the object and the controller S function, as well as the Simulink module files, a full realization of the inverted pendulum process, published an article very useful)

1.参数的设计 1）系统的变量比较多而且应用非常频繁，所以运用的变量要具有特征性 2）尽量使用课本上的变量，如果课本上的变量无法实现，在考虑其他自己定义变量 3）由于MATLAB使用变量可以不用先定义生命变量，所以可以直接使用变量 4）但是一些全局性的变量必须要定义( 1. Parameter design 1) system variables and the application is more frequent, so the use of the variable to have the characteristics of 2) the use of textbooks on the variables as possible, if the books can not be achieved on the variables, taking into account their other define the variable 3) use of the MATLAB variable life and variable can not be defined, so you can directly use the variable 4), but some global variables must be defined)
