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.
