文件有两份电梯设计的毕业论文，使用PLC设计(File has two elevator design graduation thesis, using the PLC design)

HART通用压力变送器的设计压力变送器采用的传感器通常需要不同电路与之配合使用，这就造成产品种类较多，不宜量产。一种崭新的设计思想，设计出的新型电路可以提供软件可控的恒压、恒流输出给传感器，并可以采集两路差分或四路单端输入信号。(HART universal pressure transmitter pressure transmitter used in the design of sensors usually used in conjunction with the different circuits, which result in more product categories, not mass production. A brand new design ideas, to design a new circuit can provide software controlled constant voltage, constant current output to the sensor and can capture two-way differential or four single-ended input signals.)

Linux From Scratch的中文指导,学习LINUX很有用(Linux From Scratch the Chinese guide, learning useful LINUX)

对采集到的电压信号进行小波包分解提取特征向量，再进行BP神经网络训练(On the acquisition of the voltage signal to the wavelet packet decomposition to extract feature vector and then BP neural network training)

说明：  这是一个关于数字交流电压表的设计方案，详细介绍了硬件及软件设计(This is a study on digital AC voltage meter design, detailed hardware and software design)

本程序是移动通信中多径衰落信道的Matlab仿真，对移动通信中的瑞利信道、高斯白噪声信道、伦琴信道给出了simulink的系统模型，并在MATLAB中编写程序仿真。(This program is used for simulating the multi-path fading channel in mobile communication. The simulation tool is matlab. Rayleigh fading model,AWGN model and Rician fading modle is given in simulink.)

介绍了一种使用马赫-曾德调制器产生毫米波的ROF系统，有仿真验证结果。(Describes a use of Mach- Zehnder modulator generated millimeter wave ROF system, a simulation experiment.)
