Book Description
With the advent of integrated circuits (IC), digital systems havebecome widely used in modern electronic devices, includingcommunications and measurement equipment. Direct Digital FrequencySynthesizers (DDS) are used in communications as transmitterexciters and local oscillators in receivers. The advantages aresuperior frequency stability, the same as that of the driving clockoscillator, and short switching times. The difficulties are loweroutput frequencies and rather large spurious signals. Compiled for practicing engineers who do not have theprerequisite of a specialist's knowledge in Direct DigitalFrequency Synthesizers (DDS), this collection of 40 importantreprinted papers and 9 never-before published contributionspresents a comprehensive introduction to DDS properties and a clearunderstanding of actual devices. The information in this volume canlead to easier computer simulations and improved designs. Featured topics include: * Discussion of principles and state of the art of wide-rangeDDS * Investigation of spurious signals in DDS * Combination of DDS with Phase Lock Loops (PLL) * Examination of phase and background 'noise' in DDS * Introduction to Digital to Analog Conversion (DAC) * Analysis of mathematics of quasiperiodic omission ofpulses DDFS can also serve as a textbook for students seeking essentialbackground theory.

Book Description
This thoroughly updated third edition of an Artech House bestseller brings together a team of leading experts providing a current and comprehensive treatment of global navigation satellite systems (GNSS) that readers won’t find in other resources. Packed with brand new material, this third edition includes new chapters on the system engineering details of GPS, European Galileo system, Chinese Beidou systems, GLONASS, and regional systems, such as Quasi–Zenith Satellite System (QZSS) and Navigation with Indian Constellation (NavIC). Readers also find new coverage of GNSS receivers, disruptions, errors, stand-alone GNSS performance, differential and precise point positioning. This single-source reference provides both a quick overview of GNSS essentials and an in-depth treatment of advanced topics and explores all the latest advances in technology, applications, and systems. Readers are guided in the development of new applications and on how to evaluate their performance. It explains all the differential GNSS services available to help decide which is best for a particular application. The book discusses the integration of GNSS with other sensors and network assistance. Readers learn how to build GNSS receivers and integrate them into navigational and communications equipment. Moreover, this unique volume helps determine how technology is affecting the marketplace and where best to invest in a company’s resources.
