Applications of phase-locked loops play an increasingly important role in modern electronic systems, and the last 25 years have seen new developments in the underlying theories as well. Phase-Locked Loops presents the latest information on the basic theory and applications of PLLs. Organized in a logical format, it first introduces the subject in a qualitative manner and discusses key applications. Next, it develops basic models for components of a PLL, and these are used to develop a basic PLL model. The text then discusses both linear and nonlinear methods that are used to analyze the basic PLL model. This book includes extensive coverage of the nonlinear behavior of phase-locked loops, an important area of this field and one where exciting new research is being performed. No other book available covers this critical area in such careful detail. Improvements brought about by the advent of the personal computer, especially in the use of numerical results, are integrated into the text. This book also focuses on PLL component technologies used in system implementation.

One of the most exciting theories to emerge from cognitive science research over the past few decades has been Douglas Hofstadter's notion of strange loops, from Gödel, Escher, Bach (1979). Hofstadter is also an active literary translator who has written about translation, perhaps most notably in his 1997 book Le Ton Beau de Marot, where he draws on his cognitive science research. And yet he has never considered the possibility that translation might itself be a strange loop. In this book Douglas Robinson puts Hofstadter's strange-loops theory into dialogue with a series of definitive theories of translation, in the process showing just how cognitively and affectively complex an activity translation actually is.

In this book the theory of binary systems is considered as a part of group theory and, in particular, within the framework of Lie groups. The novelty is the consequent treatment of topological and differentiable loops as topological and differentiable sections in Lie groups. The interplay of methods and tools from group theory, differential geometry and topology, symmetric spaces, topological geometry, and the theory of foliations is what gives a special flavour to the results presented in this book. It is the first monograph devoted to the study of global loops. So far books on differentiable loops deal with local loops only. This theory can only be used partially for the theory of global loops since non-associative local structures have, in general, no global forms. The text is addressed to researchers in non-associative algebra and foundations of geometry. It should prove enlightening to a broad range of readers, including mathematicians working in group theory, the theory of Lie groups, in differential and topological geometry, and in algebraic groups. The authors have produced a text that is suitable not only for a graduate course, but also for selfstudy in the subjectby interested graduate students. Moreover, the material presented can be used for lectures and seminars in algebra, topological algebra and geometry.

You read a book, you recommend it to a friend. That friend tells another friend. And another... until the book becomes this year's word-of-mouth sensation. This is the first to analyze the power of the 'pass-it-on' phenomenon, introducing us to the architects of the mightily efficient, money-spinning model known as the Viral Loop - the secret behind some of the most successful businesses in recent history. Outfits such as Google, eBay, Flickr and Facebook all employ the model at their core; all have seen their stock valuations skyrocket within years of forming. The genius lies in the model's reliance on replication: what's the point of using Facebook if none of your friends can see your profile, or using Flickr if you can't share your photos? Where's the joy in posting a video on YouTube if no one watches it? In creating a viral product that people want, need and desire, growth can, and will, take care of itself. Find out why the Loop will catch us all up, sooner rather than later...

Phase-Locked Loops for Wireless Communications: Digitial, Analog and Optical Implementations, Second Edition presents a complete tutorial of phase-locked loops from analog implementations to digital and optical designs. The text establishes a thorough foundation of continuous-time analysis techniques and maintains a consistent notation as discrete-time and non-uniform sampling are presented. New to this edition is a complete treatment of charge pumps and the complementary sequential phase detector. Another important change is the increased use of MATLAB®, implemented to provide more familiar graphics and reader-derived phase-locked loop simulation. Frequency synthesizers and digital divider analysis/techniques have been added to this second edition. Perhaps most distinctive is the chapter on optical phase-locked loops that begins with sections discussing components such as lasers and photodetectors and finishing with homodyne and heterodyne loops. Starting with a historical overview, presenting analog, digital, and optical PLLs, discussing phase noise analysis, and including circuits/algorithms for data synchronization, this volume contains new techniques being used in this field. Highlights of the Second Edition: Development of phase-locked loops from analog to digital and optical, with consistent notation throughout; Expanded coverage of the loop filters used to design second and third order PLLs; Design examples on delay-locked loops used to synchronize circuits on CPUs and ASICS; New material on digital dividers that dominate a frequency synthesizer's noise floor. Techniques to analytically estimate the phase noise of a divider; Presentation of optical phase-locked loops with primers on the optical components and fundamentals of optical mixing; Section on automatic frequency control to provide frequency-locking of the lasers instead of phase-locking; Presentation of charge pumps, counters, and delay-locked loops. The Second Edition includes the essential topics needed by wireless, optics, and the traditional phase-locked loop specialists to design circuits and software algorithms. All of the material has been updated throughout the book.

Phase lock loop frequency synthesis finds uses in a myriad of wireless applications - from local oscillators for receivers and transmitters to high performance RF test equipment. As the security and reliability of mobile communication transmissions have gained importance, PLL and frequency synthesisers have become increasingly topical subjects. Phase Lock Loops & Frequency Synthesis examines the various components that make up the phase lock loop design, including oscillators (crystal, voltage controlled), dividers and phase detectors. Interaction amongst the various components are also discussed. Real world problems such as power supply noise, shielding, grounding and isolation are given comprehensive coverage and solved examples with MATHCAD programs are presented throughout. * Presents a comprehesive study of phase lock loops and frequency synthesis in communication systems * Written by an internationally-recognised expert in the field * Details the problem of spurious signals in PLL frequency synthesizers, a topic neglected by available competing titles * Provides detailed theorectical background coupled with practical examples of state-of-the-art device design * MATHCAD programs and simulation software to accompany the design exercises and examples This combination of thorough theoretical treatment and guidance on practical applications will appeal to mobile communication circuit designers and advanced electrical engineering students.

Classical Feedback Control with Nonlinear Multi-Loop Systems describes the design of high-performance feedback control systems, emphasizing the frequency-domain approach widely used in practical engineering. It presents design methods for high-order nonlinear single- and multi-loop controllers with efficient analog and digital implementations. Bode integrals are employed to estimate the available system performance and to determine the ideal frequency responses that maximize the disturbance rejection and feedback bandwidth. Nonlinear dynamic compensators provide global stability and improve transient responses. This book serves as a unique text for an advanced course in control system engineering, and as a valuable reference for practicing engineers competing in today’s industrial environment.

ThiS is not only a book of instruction in chainmaking but it is also a work celebrating man's continuous creativity over thousands of years. At times something that man creates has far-reach ing effects; an example that quickly comes to mind is the wheel, which has enabled many devel opments, from pottery to computers. At this point it is important to note that these same wheels could not have been made without metal tools. From early Neolithic times on gold was a favorite choice in the making of jewelry. During the Neolithic period these "shining stones," probably alluvial, were prized. Actually gold was cold worked as if it were a stone. There is a surviving example of cold-worked gold from Catahuyuk (present day Turkey) estimated to have been made in 6500 B. C. There were only four metals on the earth's surface that were found in sufficient quantity to be used: gold, copper, silver, and meteoric iron. An understanding of the malleability of gold, and of the annealing effect of fire, changed jewelry making; new forms were found. Gold was no longer a piece of stone but a material that could be flattened and made very thin. Sheet and foil are the oldest forms of worked gold. The smiths' tools were stone, wood, and horn.

For the past ten years, alternative loop rings have intrigued mathematicians from a wide cross-section of modern algebra. As a consequence, the theory of alternative loop rings has grown tremendously. One of the main developments is the complete characterization of loops which have an alternative but not associative, loop ring. Furthermore, there is a very close relationship between the algebraic structures of loop rings and of group rings over 2-groups. Another major topic of research is the study of the unit loop of the integral loop ring. Here the interaction between loop rings and group rings is of immense interest. This is the first survey of the theory of alternative loop rings and related issues. Due to the strong interaction between loop rings and certain group rings, many results on group rings have been included, some of which are published for the first time. The authors often provide a new viewpoint and novel, elementary proofs in cases where results are already known. The authors assume only that the reader is familiar with basic ring-theoretic and group-theoretic concepts. They present a work which is very much self-contained. It is thus a valuable reference to the student as well as the research mathematician. An extensive bibliography of references which are either directly relevant to the text or which offer supplementary material of interest, are also included.
