Download or read book Phase Locked and Frequency Feedback Systems written by Jacob Klapper and published by Elsevier. This book was released on 2012-12-02 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase-Locked and Frequency-Feedback Systems: Principles and Techniques presents the operating principles and methods of design of phase-locked and frequency-feedback systems. This book is divided into 10 chapters that provide step-by-step design procedures and graphical aids, with illustrations bearing on real problems experienced in these systems. This work specifically tackles the application of these systems as FM demodulators with lowered thresholds. Chapters 1 and 2 deal briefly with the elements of linear systems, feedback theory, and noise, providing the minimum background for the material presented in the remainder of the text. Chapter 3 describes the characteristics of the major components that comprise the loops and the performance of the conventional and multi-loop FM demodulators. Chapters 4 to 7 present the basic describing equations and design for the FM feedback (FMFB) and phase-locked loop (PLL). These chapters further illustrate step-by-step design procedures with performance characteristics for low-threshold angle demodulation using typical design examples. Chapter 8 highlights the design principles, which are extended to the design of advanced demodulators featuring demodulation thresholds lower than those of the simple PLL or FMFB. Chapter 9 focuses on digital FM demodulation and PLL applications other than FM demodulation. Lastly, Chapter 10 presents the methods of testing and evaluating loop performance. Undergraduate and graduate level students, as well as practicing engineers, will find this book invaluable.

Download or read book Handbook on Satellite Communications written by International Telecommunications Union and published by John Wiley & Sons. This book was released on 2002-04-04 with total page 1123 pages. Available in PDF, EPUB and Kindle. Book excerpt: An essential overview of satellite communications from the organization that sets the international standards Since their introduction in the mid-1960s, satellite communications have grown from a futuristic experiment into an integral part of today's "wired world." Satellite communications are at the core of a global, automatically switched telephony network. Assembled by the International Telecommunication Union--the international organization that sets the standards for this rapidly growing industry--the Handbook on Satellite Communications, Third Edition brings together basic facts about satellite communications as related to the fixed-satellite service (FSS). It covers the main principles, technologies, and operation of equipment in a tutorial form. Updated to include the latest technologies and information, the Third Edition provides both the standards and technical information needed to implement and interact with satellite communication systems, including: * The components and basic characteristics of a satellite communication system * Regulatory considerations and system planning * SDH and ATM satellite transmissions * Analog and digital baseband signal processing and multiplexing * Carrier modulation techniques * Geostationary and non-geostationary systems * Interconnection of satellite and terrestrial networks * LEOS satellite networks and other recent developments As digital modulation and transmission replace analog techniques, and as satellites in non-geostationary and lower-altitude orbits open the way to new applications, satellite communications will continue to grow in use and importance. Everyone involved in the administration and operation of satellite communications will find this a crucial resource.

Download or read book The Neurophysiological Bases of Auditory Perception written by Enrique Lopez-Poveda and published by Springer Science & Business Media. This book was released on 2010-03-23 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the 15th International Symposium on Hearing (ISH), which was held at the Hotel Regio, Santa Marta de Tormes, Salamanca, Spain, between 1st and 5th June 2009. Since its inception in 1969, this Symposium has been a forum of excellence for debating the neurophysiological basis of auditory perception, with computational models as tools to test and unify physiological and perceptual theories. Every paper in this symposium includes two of the following: auditory physiology, psychoph- ics or modeling. The topics range from cochlear physiology to auditory attention and learning. While the symposium is always hosted by European countries, p- ticipants come from all over the world and are among the leaders in their fields. The result is an outstanding symposium, which has been described by some as a “world summit of auditory research. ” The current volume has a bottom-up structure from “simpler” physiological to more “complex” perceptual phenomena and follows the order of presentations at the meeting. Parts I to III are dedicated to information processing in the peripheral au- tory system and its implications for auditory masking, spectral processing, and c- ing. Part IV focuses on the physiological bases of pitch and timbre perception. Part V is dedicated to binaural hearing. Parts VI and VII cover recent advances in und- standing speech processing and perception and auditory scene analysis. Part VIII focuses on the neurophysiological bases of novelty detection, attention, and learning.
