Number theory as studied by the logician is the subject matter of the book. This first volume can stand on its own as a somewhat unorthodox introduction to mathematical logic for undergraduates, dealing with the usual introductory material: recursion theory, first-order logic, completeness, incompleteness, and undecidability. In addition, its second chapter contains the most complete logical discussion of Diophantine Decision Problems available anywhere, taking the reader right up to the frontiers of research (yet remaining accessible to the undergraduate). The first and third chapters also offer greater depth and breadth in logico-arithmetical matters than can be found in existing logic texts. Each chapter contains numerous exercises, historical and other comments aimed at developing the student's perspective on the subject, and a partially annotated bibliography.

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.

Branding Television examines why and how the UK and US television industries have turned towards branding as a strategy in response to the rise of satellite, cable and digital television, and new media, such as the internet and mobile phone. This is the first book to offer a sustained critical analysis of this new cultural development. Branding Television examines the industrial, regulatory and technological changes since the 1980s in the UK and the USA that have led to the adoption of branding as broadcasters have attempted to manage the behaviour of viewers and the values associated with their channels, services and programmes in a world of increased choice and interactivity. Wide-ranging case studies drawn from commercial, public service, network and cable/satellite television (from NBC and HBO to MTV, and from BBC and Channel 4 to UKTV and Sky) analyse the role of marketing and design in branding channels and corporations, and the development of programmes as brands. Exploring both successful and controversial uses of branding, this book asks what problems there are in creating television brands and whether branding supports or undermines commercial and public service broadcasting. Branding Television extends and complicates our understanding of the changes to television over the past 30 years and of the role of branding in contemporary Western culture. It will be of particular interest to students and researchers in television studies, but also in creative industries and media and cultural studies more generally.
