Communications using the high frequency spectrum (2--30 MHz) have experienced a considerable resurgence. In recent years, powerful microcomputers and VLSI technology have greatly enhanced the prospects of overcoming many of the unique problems that formerly afflicted the HF systems designer. The aim of this book, therefore, is to provide a firm foundation for the design, evaluation and operational use of HF communications, with systems issues as the primary perspective. The approach provides an understanding of the way in which various elements of the system contribute to the overall HF communications link performance. Mathematics is introduced only where needed to clarify or illustrate key issues. The book will be vital to the professional communications engineer, already familiar with many of the problems but requiring a consolidated systems view of the subject; to the engineering student and research worker as a reference text which demonstrates how modern technology can be used to solve problems posed to the HF user; and to non- specialists and consultants within the communications industry.

The ability to process signals at multiple sampling rates can help reduce costs and improve performance in many DSP applications ranging from signal compression to wireless communications, consumer entertainment products and sensor networks. The theory of multirate signal processing has witnessed a great deal of progress since the publication of the first textbook by Ronald E. Crochiere and Lawrence R. Rabiner in 1983. However, this progress has been mainly in the area of deterministic systems with emphasis on perfect-reconstruction filter banks, orthogonal filter banks, systems with the same sampling rate across all channels and tree-structured systems.

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 loopsThe quadricorrelator method for both continuous and sampled modesSawtooth ramp-and-sample phase detector and how its waveform contains frequency error information that can be extractedThe benefits of a self-sweeping, self-extinguishing topologySweep methods using quadrature mixer-based lock detectionThe 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.Errata can be found by visiting the Book Support Site at: http: //booksupport.wiley.com

Telegraphy in the nineteenth century approximated the internet in our own day. Historian and electrical engineer David Hochfelder offers readers a comprehensive history of this groundbreaking technology, which employs breaks in an electrical current to send code along miles of wire. "The Telegraph in America, 1832-1920," examines the correlation between technological innovation and social change and shows how this transformative relationship helps us to understand and perhaps define modernity.

The telegraph revolutionized the spread of information--speeding personal messages, news of public events, and details of stock fluctuations. During the Civil War, telegraphed intelligence and high-level directives gave the Union war effort a critical advantage. Afterward, the telegraph helped build and break fortunes and, along with the railroad, altered the way Americans thought about time and space. Hochfelder thus supplies us with an introduction to the early stirrings of the information age.
