Digital Circuit Boards
by Ralph MorrisonA unique, practical approach to the design of high-speed digital circuit boards<P><P> The demand for ever-faster digital circuit designs is beginning to render the circuit theory used by engineers ineffective. Digital Circuit Boards presents an alternative to the circuit theory approach, emphasizing energy flow rather than just signal interconnection to explain logic circuit behavior.<P> The book shows how treating design in terms of transmission lines will ensure that the logic will function, addressing both storage and movement of electrical energy on these lines. It covers transmission lines in all forms to illustrate how trace geometry defines where the signals can travel, then goes on to examine transmission lines as energy sources, the true nature of decoupling, types of resonances, ground bounce, cross talk, and more.<P> Providing designers with the tools they need to lay out digital circuit boards for fast logic and to get designs working the first time around, Digital Circuit Boards:<P> * Reviews in simple terms the basic physics necessary to understand fast logic design<P> * Debunks the idea that electrical conductors carry power and signals, showing that signal travels in the spaces, not the traces, of circuit boards<P> * Explains logic circuit behavior through real-time analysis involving the fields and waves that carry signal and energy<P> * Provides new information on how ground/power planes work<P> * Outlines a software program for solving energy flow in complex networks<P> Advisory: Bookshare has learned that this book offers only partial accessibility.

Digital Cities: The Interdisciplinary Future of the Urban Geo-Humanities
by Benjamin FraserDigital Cities stakes claim to an interdisciplinary terrain where the humanities and social sciences combine with digital methods. Part I: Layers of the Interdisciplinary City converts a century of urban thinking into concise insights destined for digital application. Part II: Disciplinary/Digital Debates and the Urban Phenomenon delves into the bumpy history and uneven present landscape of interdisciplinary collaboration as they relate to digital urban projects. Part III: Toward a Theory of Digital Cities harnesses Henri Lefebvre's capacious urban thinking and articulation of urban 'levels' to showcase where 'deep maps' and 'thick mapping' might take us. Benjamin Fraser argues that while disciplinary frictions still condition the potential of digital projects, the nature of the urban phenomenon pushes us toward an interdisciplinary and digital future where the primacy of cities is assured.

Digital Communication and Learning: Changes and Challenges (Educational Communications and Technology Yearbook)
by Anna Wing Bo Tso Alex Chi-keung Chan Wendy Wing Lam Chan Peter Edward Sidorko Will W. K. MaThis edited book collects papers with perspectives from scholars and practitioners in Asia, Australia, and Europe to reveal the pros and cons, chances and challenges, constraints, and potential risks that educators and learners are facing as the new paradigm for communication and learning takes place, with a view to shedding light on the global education climate in the midst of the pandemic. Since the onset of the global pandemic, education has been revolutionized in almost every aspect. The emergency precautionary measures which were once supposed to be temporary school arrangements only have now become the new normal, reshaping our understanding of learning environments, redefining the pedagogic standards in terms of teaching practices, learning designs, teacher–student interaction, feedback, and assessment. Online teaching, distanced learning, flipped classrooms, and self-paced e-learning have all played an increasingly vital role in shaping a new education culture in various education settings, affecting school management, teachers, students, and parents alike. While ICT in education, alongside new media, has provided ample benefits and convenience for educators and students, communication and virtual lessons conducted in the socially distanced classroom appear to have brought issues such as the digital divide, e-mental health, insufficient technical support, inefficient classroom management, reduced interaction between teachers and students, not to mention the growing concerns over privacy and security.

Digital Communications 1: Source and Channel Coding
by Didier Le Ruyet Mylène PischellaThe communication chain is constituted by a source and a recipient, separated by a transmission channel which may represent a portion of cable, an optical fiber, a radio channel, or a satellite link. Whatever the channel, the processing blocks implemented in the communication chain have the same foundation. This book aims to itemize. In this first volume, after having presented the base of the information theory, we will study the source coding techniques with and without loss. Then we analyze the correcting codes for block errors, convutional and concatenated used in current systems.
Digital Communications 2: Directed and Practical Work
by Safwan El Assad Dominique BarbaIt is a complete training in digital communications in the same book with all the aspects involved in such training: courses, tutorials with many typical problems targeted with detailed solutions, practical work concretely illustrating various aspects of technical implementation implemented. It breaks down into three parts. The Theory of information itself, which concerns both the sources of information and the channels of its transmission, taking into account the errors they introduce in the transmission of information and the means of protect by the use of appropriate coding methods. Then for the technical aspects of transmission, first the baseband transmission is presented with the important concept and fundamental technique of equalization. The performance evaluation in terms of probability of errors is systematically developed and detailed as well as the online codes used. Finally, the third part presents the Transmissions with digital modulation of carriers used in radio transmissions but also on electric cables. A second important aspect in learning a learner's knowledge and skills is this book. It concerns the "Directed Work" aspect of a training. This is an ordered set of 33 typical problems with detailed solutions covering the different parts of the course with practical work. Finally, the last aspect concerns the practical aspects in the proper sense of the term, an essential complement to training going as far as know-how. We propose here a set of 5 practical works.

Digital Constitutionalism: The Role of Internet Bills of Rights (Routledge Research in the Law of Emerging Technologies)
by Edoardo CelesteInvestigating the impact of digital technology on contemporary constitutionalism, this book offers an overview of the transformations that are currently occurring at constitutional level, highlighting their link with ongoing societal changes. It reconstructs the multiple ways in which constitutional law is reacting to these challenges and explores the role of one original response to this phenomenon: the emergence of Internet bills of rights. Over the past few years, a significant number of Internet bills of rights have emerged around the world. These documents represent non-legally binding declarations promoted mostly by individuals and civil society groups that articulate rights and principles for the digital society. This book argues that these initiatives reflect a change in the constitutional ecosystem. The transformations prompted by the digital revolution in our society ferment under a vault of constitutional norms shaped for ‘analogue’ communities. Constitutional law struggles to address all the challenges of the digital environment. In this context, Internet bills of rights, by emerging outside traditional institutional processes, represent a unique response to suggest new constitutional solutions for the digital age. Explaining how constitutional law is reacting to the advent of the digital revolution and analysing the constitutional function of Internet Bills of Rights in this context, this book offers a global comparative investigation of the latest transformations that digital technology is generating in the constitutional ecosystem and highlights the plural and multilevel process that is contributing to shape constitutional norms for the Internet age.
