Radio and Line Transmission, Volume 2 gives a detailed treatment of the subject as well as an introduction to additional advanced subject matter. Organized into 14 chapters, this book begins by explaining the radio wave propagation, signal frequencies, and bandwidth. Subsequent chapters describe the transmission lines and cables; the aerials; tuned and coupled circuits; bipolar transistor amplifiers; field-effect transistors and circuits; thermionic valve amplifiers; LC oscillators; the diode detectors and modulators; and the superheterodyne receiver. Other chapters explore noise and interference in the transmission; the negative feedback that occurs in amplifier; and the methods used in the field of electronic measurements. This volume will be very valuable to technicians in the electrical engineering industry.

Radio and Line Transmission, Volume 1 provides an introduction to the basic principles of radio and line transmission. This book serves as a guide for technicians in the electrical engineering industry. Organized into 14 chapters, this volume starts with an overview of the definition of wave motion, which is a significant concept in the study of communications methods. This text then explains decibel as the most convenient practical unit based on logarithms. Other chapters consider the frequency ranges for speech and music. This book describes as well the harmonic composition of sound waves and the frequency analysis of speech. The final chapter presents the fundamental feature of all telegraph systems, which is the use of codes such as the Morse code, cable code, and the five-unit even-length code. This book is a valuable resource for electrical technicians engaged in radio communications. Senior technicians on national certificate courses will also find this book extremely useful.

Fossil-fuel power plants account for the majority of worldwide power generation. Increasing global energy demands, coupled with issues of ageing and inefficient power plants, have led to new power plant construction programmes. As cheaper fossil fuel resources are exhausted and emissions criteria are tightened, utilities are turning to power plants designed with performance in mind to satisfy requirements for improved capacity, efficiency, and environmental characteristics.Advanced power plant materials, design and technology provides a comprehensive reference on the state of the art of gas-fired and coal-fired power plants, their major components and performance improvement options. Part one critically reviews advanced power plant designs which target both higher efficiency and flexible operation, including reviews of combined cycle technology and materials performance issues.Part two reviews major plant components for improved operation, including advanced membrane technology for both hydrogen (H2) and carbon dioxide (CO2) separation, as well as flue gas handling technologies for improved emissions control of sulphur oxides (SOx), nitrogen oxides (NOx), mercury, ash and particulates. The section concludes with coverage of high-temperature sensors, and monitoring and control technology that are essential to power plant operation and performance optimisation.Part three begins with coverage of low-rank coal upgrading and biomass resource utilisation for improved power plant fuel flexibility. Routes to improve the environmental impact are also reviewed, with chapters detailing the integration of underground coal gasification and the application of carbon dioxide (CO2) capture and storage. Finally, improved generation performance is reviewed with coverage of syngas and hydrogen (H2) production from fossil-fuel feedstocks.With its distinguished international team of contributors, Advanced power plant materials, design and technology is a standard reference for all power plant engineers and operators, as well as to academics and researchers in this field.- Provides a comprehensive reference on the state-of-the-art gas-fired and coal-fired power plants, their major components and performance improvement options- Examines major plant components for improved operation as well as flue gas handling technologies for improved emissions control- Routes to improve environmental impact are discussed with chapters detailing the integration of underground coal gasification
