为了满足现代高速通信中频率快速转换的需求，基于坐标旋转数字计算（CORDIC，Coordinate Rotation Digital COMputer）算法完成正交直接数字频率合成（ODDFS，Orthogonal Direct Digital Frequency Synthesizer）电路设计方案。采用MATLAB和Xilinx System Generator开发工具搭建电路的系统模型，通过现场可编程门阵列（FPGA，Field Programmable Gate Array）完成电路的寄存器传输级（RTL，Register Transfer Level）验证，仿真结果表明电路设计具有很高的有效性和可行性。

Abstract: Alexander Graham Bell patented twisted pair wires in 1881. We still use them today because they work so well. In addition we have the advantage ofincredible COMputer power within our world. Circuit simulators and filter design programs are available for little or no cost. We combine the twisted pair and lowpassfilters to produce spectacular rejection of radio frequency interference (RFI) and electromagnetic interference (EMI). We also illustrate use of a precision resistorarray to produce a customizable differential amplifier. The precision resistors set the gain and common mode rejection ratios, while we choose the frequencyresponse.

A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Turbo" XT can acquire data at speeds greater than 20kHz. Machines with 80286 and 80386 processors can go faster than 20kHz. The COMputer that was used as a test bed in this application was an XT running at 4.77MHz and therefore all system timing and acquisition time measurements are based on a 4.77MHz clock speed.

高速数字系统设计下载pdf:High-Speed Digital SystemDesign—A Handbook ofInterconnect Theory and DesignPracticesStephen H. HallGarrett W. HallJames A. McCallA Wiley-Interscience Publication JOHN WILEY & SONS, INC.New York • Chichester • Weinheim • Brisbane • Singapore • TorontoCopyright © 2000 by John Wiley & Sons, Inc.speeddigital systems at the platform level. The book walks the reader through everyrequired concept, from basic transmission line theory to digital timing analysis, high-speedmeasurement techniques, as well as many other topics. In doing so, a unique balancebetween theory and practical applications is achieved that will allow the reader not only tounderstand the nature of the problem, but also provide practical guidance to the solution.The level of theoretical understanding is such that the reader will be equipped to see beyondthe immediate practical application and solve problems not contained within these pages.Much of the information in this book has not been needed in past digital designs but isabsolutely necessary today. Most of the information covered here is not covered in standardcollege curricula, at least not in its focus on digital design, which is arguably one of the mostsignificant industries in electrical engineering.The focus of this book is on the design of robust high-volume, high-speed digital productssuch as COMputer systems, with particular attention paid to COMputer busses. However, thetheory presented is applicable to any high-speed digital system. All of the techniquescovered in this book have been applied in industry to actual digital products that have beensuccessfully produced and sold in high volume.Practicing engineers and graduate and undergraduate students who have completed basicelectromagnetic or microwave design classes are equipped to fully comprehend the theorypresented in this book. At a practical level, however, basic circuit theory is all thebackground required to apply the formulas in this book.

1.什么是CTP? CTP包括几种含义: 脱机直接制版(COMputer-to-plate) 在机直接制版(COMputer-to-press) 直接印刷(COMputer-to-paper/print) 数字打样(COMputer-to-proof) 普通PS版直接制版技术,即CTcP(COMputer-to-conventional plate) 这里所论述的CTP系统是脱机直接制版(COMputer-to-plate)。CTP就是计算机直接到印版，是一种数字化印版成像过程。CTP直接制版机与照排机结构原理相仿。起制版设备均是用计算机直接控制，用激光扫描成像，再通过显影、定影生成直接可上机印刷的印版。计算机直接制版是采用数字化工作流程，直接将文字、图象转变为数字，直接生成印版，省去了胶片这一材料、人工拼版的过程、半自动或全自动晒版工序。
