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 Frequency Acquisition Techniques for Phase Locked Loops written by Daniel B. Talbot and published by John Wiley & Sons. This book was released on 2012-08-24 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to acquire the input frequency from an unlocked state A phase locked loop (PLL) by itself cannot become useful until it has acquired the applied signal's frequency. Often, a PLL will never reach frequency acquisition (capture) without explicit assistive circuits. Curiously, few books on PLLs treat the topic of frequency acquisition in any depth or detail. Frequency Acquisition Techniques for Phase Locked Loops offers a no-nonsense treatment that is equally useful for engineers, technicians, and managers. Since mathematical rigor for its own sake can degenerate into intellectual "rigor mortis," the author introduces readers to the basics and delivers useful information with clear language and minimal mathematics. With most of the approaches having been developed through years of experience, this completely practical guide explores methods for achieving the locked state in a variety of conditions as it examines: Performance limitations of phase/frequency detector–based phase locked loops The quadricorrelator method for both continuous and sampled modes Sawtooth ramp-and-sample phase detector and how its waveform contains frequency error information that can be extracted The benefits of a self-sweeping, self-extinguishing topology Sweep methods using quadrature mixer-based lock detection The use of digital implementations versus analog Frequency Acquisition Techniques for Phase Locked Loops is an important resource for RF/microwave engineers, in particular, circuit designers; practicing electronics engineers involved in frequency synthesis, phase locked loops, carrier or clock recovery loops, radio-frequency integrated circuit design, and aerospace electronics; and managers wanting to understand the technology of phase locked loops and frequency acquisition assistance techniques or jitter attenuating loops.

This critically acclaimed book has been thoroughly updated with new information and expanded for greater depth.
Download or read book Feedback written by Tom Moir and published by Springer Nature. This book was released on 2020-01-03 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text ventures into areas which the majority of control system books avoid. It was written to look at the area in a much wider form than the usual process control or machine control-systems. Many topics which are covered in other specialities are covered such as the stability of amplifiers, phase-locked loops, structural resonance and parasitic oscillations. It also covers the application and implementation of real-time digital controllers and for the first time the Amplitude-locked loop. An even wider look at the area is shown by examining classical or historic mathematical algorithms in terms of control-theory. Despite its wide range, the book is tutorial in nature and tries to avoid where possible an obtuse mathematical approach. It comes with MATLAB, LabView and a few Mathematica examples. The book is an ideal undergraduate text for engineers and a refresher for many practising engineers. It gives a thorough background in the analogue domain before moving on to digital-control and its applications. The proceeds from author royalties of this book will be donated to charity.

Available in PDF, EPUB and Kindle. Book excerpt: This book develops the basic concepts in understanding Analog Communications. Beginning with coverage of amplitude modulation, including the time and frequency domain representations of double sideband, single sideband, and vestigial sideband modulation, and introduces the student to the fundamental ideas of quadrature amplitude modulation, frequency division multiplexing, and digital communications using on-off keying. The author continues with additional discussion and coverage of the time and frequency domain representations of frequency and phase modulation, including bandwidth calculations, and the use of frequency shift keying, phase shift keying, and differential phase shift keying for the transmission of digital information. Contents include applications and further analyses of the effects of channel noise on amplitude, phase, and frequency modulation performance based on input versus output signal to noise ratios and some system comparisons are discussed.
