Available in PDF, EPUB and Kindle. Book excerpt: This book written by P. A. Kinzie chronicles the fascinating history and development of the crystal detector, including the reasons for its brief dominance of the radio market after the turn of the century. Starting with the discovery of solid-state rectification and then through the development of the crystal detector the reader learns about great inventors such as Pickard, Braun, Dunwoody, and others. Radio fundamentals such as antennas, ground, lightning protection, tuned circuits, and detection are covered for the beginner. The unending compromise between selectivity and sensitivity is discussed for the crystal set designer. Advanced topics such as the use of multi-tuned circuits and wave traps follow for the more experienced experimenter.The crystal set embodies many of the basic concepts upon which modern radio electronics is based. By grasping these basics in their rarest form, the crystal set, the reader can build a powerful foundation for additional learning.

Available in PDF, EPUB and Kindle. Book excerpt: One of the pleasures of crystal radio is the satisfaction of using minimal technology to receive radio signals. Crystal radio enthusiasts are great experimenters and thrill in creating "different" designs and packaging them in aesthetically pleasing ways. In my book, I provide a complete introduction to crystal radio. I start with the humble electron, layout crystal radio theory, and finish off designing and constructing a working crystal radio. As with all my "From Scratch" books, I make no assumptions about what you know about the subject. Occasionally, math is involved, but I keep it at the basic algebra level whenever possible. I also use simulation and breadboarding (actual hardware testing) to verify theory. In short, I take the mystery out of crystal radio and open possibilities for the reader to explore radio and electronic subjects beyond the limits of my book.

Available in PDF, EPUB and Kindle. Book excerpt: Quartz crystal-a technology that changed the tide of World War II Some of the defining leaps in technology in the twentieth century occurred during the Second World War, from radar to nuclear energy. Often left out of historical discussions are quartz crystals, which proved to be just as pivotal to the Allied victory-and to post-war development-as other technologies. Quartz crystals provided the U.S. military, for the first time, with reliable communication on the front lines, and then went on to become the core of some of the most basic devices of the post-war era, from watches, clocks, and color televisions, to cell phones and computers. In Crystal Clear, Richard Thompson relates the story of the quartz crystal in World War II, from its early days as a curiosity for amateur radio enthusiasts, to its use by the United States Armed Forces. It follows the intrepid group of scientists and engineers from the Office of the Chief Signal Officer of the U.S. Army as they raced to create an effective quartz crystal unit. They had to find a reliable supply of radio-quality quartz; devise methods to reach, mine, and transport the quartz; find a way to manufacture quartz crystal oscillators rapidly; and then solve the puzzling "aging problem" that plagued the early units. Ultimately, the development of quartz oscillators became the second largest scientific undertaking in World War II after the Manhattan Project. Bringing to light a little-known aspect of World War II, Crystal Clear offers a glimpse inside one of the most significant efforts in the annals of engineering.

Available in PDF, EPUB and Kindle. Book excerpt: The power consumption of integrated circuits is one of the most problematic considerations affecting the design of high-performance chips and portable devices. The study of power-saving design methodologies now must also include subjects such as systems on chips, embedded software, and the future of microelectronics. Low-Power Electronics Design covers all major aspects of low-power design of ICs in deep submicron technologies and addresses emerging topics related to future design. This volume explores, in individual chapters written by expert authors, the many low-power techniques born during the past decade. It also discusses the many different domains and disciplines that impact power consumption, including processors, complex circuits, software, CAD tools, and energy sources and management. The authors delve into what many specialists predict about the future by presenting techniques that are promising but are not yet reality. They investigate nanotechnologies, optical circuits, ad hoc networks, e-textiles, as well as human powered sources of energy. Low-Power Electronics Design delivers a complete picture of today's methods for reducing power, and also illustrates the advances in chip design that may be commonplace 10 or 15 years from now.

Book excerpt: Foxhole Radio is the story of one of the more remarkable pieces of WWII soldier improvisation, a simple crystal radio receiver that used a razor blade for its detector. It is not remarkable for its technology - other radios worked better - but because hidden in its unglamorous amalgamation of scrounged parts is the history of army radio, morale, solid state electronics, field fortifications, and even military grooming. To distract himself for a while from the monotony of sitting in a foxhole and from the sporadic shelling by the enemy, a soldier on the Anzio beachhead made the first foxhole radio to listen to whatever stations might be in range. With no crystal nor cat whisker, he substituted what was on hand, a razor blade and a safety pin.It spread, by word of mouth mostly, across the beachhead, Europe and to the Pacific. Adopted by civilian radio enthusiasts, it became part of the lore of home experimenters and grade school science projects. More than a curious artifact of wartime improvisation, the foxhole radio reveals the story of the military's role in the radio development, and an intertwined tale of army shaving, corporate intrigue, and the evolution of the radio wave detector that led to the first solid state electronics. Foxhole Radio follows the history of army radio from the first experiments in the 1890s, to its coming of age during WWI, and its use for propaganda and morale during WWII. The razor and safety pin detector reveal a conflation of standard, archaic and folk radio wave detectors, the persistence of lore, and the army's battle with facial hair. The name "foxhole radio" itself tells of early field fortifications, words borrowed from across the lines, and the evolution of military jargon. Most importantly, Foxhole Radio tells the stories of the veterans who built these sets, how they built them, what they listened to, and their everyday realities. Though separated by thousands of miles with very different experiences, they were all united by a strange little radio and their desire to hear music and news from home.

This book was released on 2007-05-08 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hardly a profound observation to note that we remain in the midst of a wireless revolution. In 1998 alone, over 150 million cell phones were sold worldwide, representing an astonishing 50% increase over the previous year. Maintaining such a remarkable growth rate requires constant innovation to decrease cost while increasing performance and functionality. Traditionally, wireless products have depended on a mixture of semicond- tor technologies, spanning GaAs, bipolar and BiCMOS, just to name a few. A question that has been hotly debated is whether CMOS could ever be suitable for RF applications. However, given the acknowledged inferiority of CMOS transistors relative to those in other candidate technologies, it has been argued by many that “CMOS RF” is an oxymoron, an endeavor best left cloistered in the ivory towers of academia. In rebuttal, there are several compelling reasons to consider CMOS for wi- less applications. Aside from the exponential device and density improvements delivered regularly by Moore’s law, only CMOS offers a technology path for integrating RF and digital elements, potentially leading to exceptionally c- pact and low-cost devices. To enable this achievement, several thorny issues need to be resolved. Among these are the problem of poor passive com- nents, broadband noise in MOSFETs, and phase noise in oscillators made with CMOS. Beyond the component level, there is also the important question of whether there are different architectural choices that one would make if CMOS were used, given the different constraints.

Book excerpt: An impassioned look at games and game design that offers the most ambitious framework for understanding them to date. As pop culture, games are as important as film or television—but game design has yet to develop a theoretical framework or critical vocabulary. In Rules of Play Katie Salen and Eric Zimmerman present a much-needed primer for this emerging field. They offer a unified model for looking at all kinds of games, from board games and sports to computer and video games. As active participants in game culture, the authors have written Rules of Play as a catalyst for innovation, filled with new concepts, strategies, and methodologies for creating and understanding games. Building an aesthetics of interactive systems, Salen and Zimmerman define core concepts like "play," "design," and "interactivity." They look at games through a series of eighteen "game design schemas," or conceptual frameworks, including games as systems of emergence and information, as contexts for social play, as a storytelling medium, and as sites of cultural resistance. Written for game scholars, game developers, and interactive designers, Rules of Play is a textbook, reference book, and theoretical guide. It is the first comprehensive attempt to establish a solid theoretical framework for the emerging discipline of game design.

Available in PDF, EPUB and Kindle. Book excerpt: The ultimate practical resource for today's RF system design professionals Radio frequency components and circuits form the backbone of today's mobile and satellite communications networks. Consequently, both practicing and aspiring industry professionals need to be able to solve ever more complex problems of RF design. Blending theoretical rigor with a wealth of practical expertise, Practical RF System Design addresses a variety of complex, real-world problems that system engineers are likely to encounter in today's burgeoning communications industry with solutions that are not easily available in the existing literature. The author, an expert in the field of RF module and system design, provides powerful techniques for analyzing real RF systems, with emphasis on some that are currently not well understood. Combining theoretical results and models with examples, he challenges readers to address such practical issues as: * How standing wave ratio affects system gain * How noise on a local oscillator will affect receiver noise figure and desensitization * How to determine the dynamic range of a cascade from module specifications * How phase noise affects system performance and where it comes from * How intermodulation products (IMs) predictably change with signal amplitude, and why they sometimes change differently An essential resource for today's RF system engineers, the text covers important topics in the areas of system noise and nonlinearity, frequency conversion, and phase noise. Along with a wealth of practical examples using MATLAB(r) and Excel, spreadsheets are available for download from an FTP Web site to help readers apply the methods outlined in this important resource.
