关于地震数据恢复的一系列论文，后面会将这一系列的论文上传。希望对处理地震数据的人有帮助。(This is a series of papers on the restoration of seismic data, the following will be uploaded to this series of papers, and I hope to be helpful to the people who deal with seismic data.)

以双向DC-DC变换器为例，通过双向控制模型的分析，采用PID 补偿环节的单电压闭环实现了BDC系统闭环稳定。(Bi-directional DC-DC converter, for example, through the analysis of the two-way control model, the single-voltage closed-loop PID compensation link to achieve a the BDC system closed-loop stable.)

改程序是郭磊，基于定向二维插值的逆投影变换方法论文中对应的程序，对于学习该篇论文的朋友有一定的帮助。(Guo Lei reform program is based on inverse projection transform paper orientation corresponding two-dimensional interpolation program for learning the papers friends will certainly help.)

题目1 FTP客户端与服务器端设计 题目2 邮件服务系统设计 题目3 HTTP通信系统设计(Title 1 FTP client and server-side design Title 2 mail service system design Title 3 HTTP communication system design)

该步进电机为一四相步进电机，采用单极性直流电源供电(The stepper motor for the 14-phase stepper motor, using unipolar DC power supply)

针对DVB-T标准ETSI EN 300 744 V1.5.1,设计了可用于DVB-T接收整机的多速率DDC模块,并在FPGA中仿真实现.在复用数字振荡混频模块的基础上,根据输入信号的不同带宽(6M/8MHz)选择不同的抽取滤波器组完成抽取因子为3或4的多速率处理任务,利用两级半带滤波器(HBF)级联完成4倍抽取滤波,单级奈奎斯特滤波器完成3倍抽取滤波. (For the DVB-T standard ETSI EN 300 744 V1.5.1, designed for DVB-T receiver machine multi-rate DDC module, and the simulation in the FPGA implementation. Numerical oscillation in the complex mixer module, based on the input signals of different bandwidths (6M/8MHz) choose a different group of complete decimation filter extracted factor 3 or 4 of the multi-rate processing tasks, using two half-band filter (HBF) cascade to complete four times decimation filter, single-stage Chennai Nyquist filter to complete three times the decimation filtering.)

The upgraded version is used to develop new devices for the chip CC2430. The guide helps to configure this details
