The comprehensive guide to planning and implementing your Cisco IP Telephony system, as shown by the experts. Understand how to work through the different implementation phases of a Cisco IP telephony solution Plan your implementation with tools and guides from the most seasoned experts in the industry Avoid pitfalls in the process with best-practice suggestions and other tips derived from years of actual implementation experience Cisco IP Telephony: Planning, Design, Implementation, and Operation of the IP Telephony Network, is a guide for network engineers as they go through the deployment of a Cisco IP telephony (IPT) solution. Although an IPT system brings several benefits to an organization, understanding all the components of that system is necessary for a successful implementation. Engineers tasked with implementation must also keep in mind that the architecture they are installing must be scalable in the future. The authors of this book, Ramesh Kaza and Salman Asadullah, have taken an approach to address the questions that come to these engineers while planning, designing, implementing, and operating the Cisco IPT solutions. The deployment process has been divided into four phases: Planning, Design, Implementation, and Operation (PDIO). Each phase provides specific details about the tasks involved and best practices for successful implementation of the IPT solution. This book also contains pre-designed questionnaires and assistance tools that will help engineers determine the requirements of each phase of the PDIO cycle. This book is written by experts from Cisco with extensive experience in implementing these solutions. Readers are provided step-by-step explanations, specific details, and best practices acquired by the authors while working with the top Cisco IPT customers.

In this book I trace the growing tension between freedom of expression and copyright law’s grant of property rights in expression. That tension cannot be eradicated: by giving authors exclusive rights, copyright both encourages the creation of new works and necessarily prevents some speakers from copying from existing expression to convey their message effectively. But while that tension is inevitable, it is not wholly irremediable. As I argue, copyright can and should be redrawn to better serve free speech goals in both traditional and digital media. I have two caveats about my project. First, due to space limitations, I focus almost entirely on the law and system of free expression in the United States. Copyright and free speech simultaneously face and embrace each other in other countries as well, and while copyright’s paradox has received first, most intensive attention in the United States, non-American scholars, lawmakers, and judges have also joined the fray, yielding much insight. I hope that my foreign colleagues will draw parallels to my exploration of the U.S. experience. Second, especially as applied to digital networks, copyright is a highly fluid area of law and policy with new, noteworthy developments taking place almost every day. Unfortunately for readers, but perhaps thankfully for tired authors, there comes a time when texts published in hard copy are put to bed and can no longer reflect ongoing developments. With isolated exceptions, this book reflects developments only through April 1, 2007. I trust that its thesis and argument will remain relevant for a good time after that, even as some of its detail is overtaken by subsequent events.

Whether you are a seasoned professional or aspiring artist, you'll find many useful ideas and techniques in this text that will improve your skills and help you create and paint masterful digital art.

This well-respected, market-leading text discusses the use of digital computers in the real-time control of dynamic systems. The emphasis is on the design of digital controls that achieve good dynamic response and small errors while using signals that are sampled in time and quantized in amplitude. Both classical and modern control methods are described and applied to illustrative examples. The strengths and limitations of each method are explored to help the reader develop solid designs with the least effort. Two new chapters have been added to the third edition offering a review of feedback control systems and an overview of digital control systems. Updated to be fully compatible with MATLAB versions 4 and 5, the text thoroughly integrates MATLAB statements and problems to offer readers a complete design picture. The new edition contains up-to-date material on state-space design and twice as many end- of-chapter problems to give students more opportunities to practice the material.

To take full advantage of the potential of modern digital control systems, this text demonstrates how to design high-performance model-based controllers using techniques extensively tested in an industrial context. Implementation issues are considered and applications illustrate the effective use of the techniques proposed. Several recent methodological developments in control design and system identification: robust digital control design using sensitivity function shaping; plant identification in closed loop operation; and reduction of controller complexity are covered, as is state space representation. The text of Digital Control Systems is enhanced by the use of software illustrating the various concepts and algorithms and gives a feeling for the phenomena, discussed. Graduate students in digital control will find this text helpful in learning the essential techniques of computer-based control while the additional material will make the tutor’s tasks of teaching and preparation quicker and easier.

Ideal for a first course in digital electronics, yet comprehensive enough for use by students at the senior design project level and EET professionals, Digital Design with CPLD Applications and VHDL uses programmable logic as the primary vehicle for instructing readers in the principles of digital design. More specifically, emphasis is on Complex Programmable Logic Devices (CPLDs) and the software tools used for their programming, with a decided shift away from fixed-function SSI and MSI devices. Immediately following discussion of digital fundamentals (e.g., Boolean algebra, logic minimization, combinational and sequential circuits), Digital Design with CPLD Applications and VHDL introduces its readers to Complex Programmable Logic Devices (CPLDs). Subsequent chapters on the MAX+PLUS II design environment, combinational logic functions, arithmetic circuits, latches and flip-flops, PLD architecture, counters and shift registers, and state machines are all based primarily on CPLDs and VHDL programming. By featuring VHDL and MAX+PLUS II applications throughout the book, readers are guaranteed exposure to this new digital paradigm as an integral part of their training, rather than as an optional add-on. Digital Design with CPLD Applications and VHDL also includes a CD-ROM that provides the reader with a complete digital design and prototyping system that can be used at school…or at home. Included are graphic design files, VHDL files, plus all of the simulation files from the examples presented in the book. Readers may opt to run simulations or program CPLDs with these ready-to-use, error-free files. Or, they may choose to use the files as templates for their own modifications.

The Kanazawa Institute of Technology is Japan's largest institution of higher education specializing in engineering and technology. It is a world leader and collaborator in electronic initiatives, often on the forefront of systems design and telecommunications advancement. It is also the site of an annual symposium series on digital library development. Marcum and George have pulled together an international cadre of leading thinkers and experimenters, all of whom have participated in these symposia, to provide their considered opinions concerning the influence of digital technology on teaching and learning in general, and the role of the library in the educational enterprise in particular. Their contributions have, in turn, been arranged into four thematic groupings, which range from envisioning the future, and facing major challenges, to creating projects and programs, and developing digital libraries. An informative read for anyone involved in higher education.

The purpose of this book is to provide a theory of Digital Power Electronics and its applications. It is well organized in 400 pages and over 300 diagrams. Traditionally, Power Electronics is analyzed by the analog control theory. For over a century, people have enjoyed analog control in Power Electronics, and good results in the analog control and its applications in Power Electronics mislead people into an incorrect conclusion that Power Electronics must be in analog control scheme. The mature control results allowed people to think that Power Electronics is a sunset knowledge.We would like to change these incorrect conclusions, and confer new life onto the traditional Power Electronics. In this book the authors initially introduce the digital control theory applied to Power Electronics, which is completely different from the traditional control scheme.

Digital signal processing (DSP) refers to anything that can be done to a signal using code on a computer or DSP chip. To reduce certain sinusoidal frequency components in a signal in amplitude, digital filtering is done. One may want to obtain the integral of a signal. If the signal comes from a tachometer, the integral gives the position. If the signal is noisy, then filtering the signal to reduce the amplitudes of the noise frequencies improves signal quality. For example, noise may occur from wind or rain at an outdoor music presentation. Filtering out sinusoidal components of the signal that occur at frequencies that cannot be produced by the music itself results in recording the music with little wind and rain noise. Sometimes the signal is corrupted not by noise, but by other signal frequencies that are of no present interest. If the signal is an electronic measurement of a brain wave obtained by using probes applied externally to the head, other electronic signals are picked up by the probes, but the physician may be interested only in signals occurring at a particular frequency. By using digital filtering, the signals of interest only can be presented to the physician.
