This comprehensive book covers spectral analysis theory for radio signals and innovative devices designed for filtering electromagnetic waves across diverse frequency ranges. The book features 14 chapters that explain the working of devices utilizing surface and bulk acoustic waves. The chapters provide insights into acousto-optical and acousto-electronic Fourier processors' design principles, description methods, and characteristics. The inclusion of algorithms for multi-channel frequency discriminators enhances the precision of radio signal frequency measurements, ensuring stability in tracking frequency meters amidst intense interference. The book also includes mathematical modeling and experimental studies of waveguide microwave filters and X-band multiplexers, specifically tailored for non-pressurized radio electronic equipment in space communication systems. Notably, the book introduces readers to a compelling alternative to conventional filters: 2-D periodic structures in the form of thin perforated metal meshes that offer compact solutions for millimeter and sub-millimeter wave systems. A significant portion of the book is dedicated to the development of highly selective microstrip filters, incorporating complex topological structures with limited resonators and numerous couplings. This approach allows for the formation of numerous attenuation poles at finite frequencies, facilitating the achievement of high electrical parameters and compact filter sizes.

Overview of the end-to-end process of planning, undertaking, and reporting of forensic radio surveying to support cell site analysis. The newly updated and revised Second Edition of Forensic Radio Survey Techniques for Cell Site Analysis provides an overview of the end-to-end process of planning, undertaking, and reporting of forensic radio surveying to support the forensic discipline of cell site analysis. It starts by recapping and explaining, in an accessible way, the theory, structure, and operation of cellular communications networks, then moves on to describe the techniques and devices employed to undertake forensic radio surveys. Worked examples are used throughout to demonstrate the practical steps required to plan and undertake forensic radio surveys, including the methods used to analyze radio survey data and compile it into a court report. A summary section condenses the technical and practical elements of the book into a handy reference resource for busy practitioners. The Second Edition contains 25% brand new material covering 5G New Radio networks and '6G and beyond,' critical communications, mobile satellite communications, IoT networks, Cell Site Analysis Tools, and much more.

In his characteristic accessible and clear style, R.H. Warring offers a guide for the radio amateur to many of the things one ought to know when tackling a radio project. Warring describes and illustrates the design and working characteristics of the basic electronic 'blocks' from which radio receivers can be constructed and shows the reader how to incorporate additional simple circuits, such as volume and tone controls, and automatic gain control, to build upon these basic blocks. Straightforward calculations are provided to determine the values of components like resistors, capacitors and inductances to optimise your results. Building and Designing Transistor Radios will equip you with the skills and knowledge properly to understand transistor radios. Special attention is paid to the transistor, the most important component, which the author provides insightful advice on. By understanding the operating characteristics of the radio's different elements, the reader can learn how to devise circuits so that they perform most efficiently. With 80 diagrams, no excessively complicated circuitry, and minimal mathematical calculations included.
