Do you need to know what signal type to select for a wireless application? Quickly develop a useful expertise in digital modulation with this practical guide, based on the author's experience of over thirty years in industrial design. You will understand the physical meaning behind the mathematics of wireless signals and learn the intricacies and tradeoffs in signal selection and design. Six modulation families and twelve modulation types are covered in depth, together with a quantitative ranking of relative cost incurred to implement any of twelve modulation types. Extensive discussions of the Shannon Limit, Nyquist filtering, efficiency measures and signal-to-noise measures are provided, radio wave propagation and antennas, multiple access techniques, and signal coding principles are all covered, and spread spectrum and wireless system operation requirements are presented.

Learn how envelope tracking, polar modulation, and hybrid designs using these techniques, really work. The first physically based and coherent book to bring together a complete overview of such circuit techniques, this is an invaluable resource for practising engineers, researchers and graduate students working on RF power amplifiers and transmitters. Learn how to create more successful designs. • Step-by-step design guidelines and real world case studies show you how to put these techniques into practice • A survey of how various transistor technologies help you to choose which transistor type to use for best results • Detail on the test and measurement of all aspects of these designs explains how to measure what the circuit is actually doing and how to interpret measurement results.

The history of Shakespearean performance is very well served at its two extremes, with volumes providing a valuable historical overview of the subject and others concentrating on the performance history of a particular play. However, no individual volume provides an in-depth consideration of the stage histories of a number of plays, chosen for their particular significance within specific cultural contexts. Shakespeare in Stages addresses this gap. The original case studies explore significant anglophone performances of the plays, as well as ideas about 'Shakespeare', through the changing prisms of three different cultural factors that have proved influential in the way Shakespeare is staged: notions of authenticity, attitudes towards sex and gender, and questions of identity. Ranging from the sixteenth to the twenty-first centuries and examining productions of plays in Britain, USA, Canada, Australia, and South Africa, the studies focus attention on the complex interaction between particular plays, issues, events, and periods.
