This updated edition of the industry's classic text combines the theory, practice, and latest technology of spectrum and network measurements in electronic systems to offer a comprehensive and easy way to understand frequency domain measurements. Spectrum and Network Measurements, 2nd Edition has been completely updated to take into account the latest technology, particularly focusing on the shift from analog to digital in communication systems, plus an important new chapter on EMC measurements of radiated and conducted emissions has also been added. Using simplified block diagrams, this book offers a thorough coverage of critical concepts, such as decibels, Fourier analysis, noise effects, impedance matching, intermodulation distortion, reflection measurements, and S-Parameters. By picking up where the majority of electrical engineering programs stop, this title takes basic EE theory and translates it to the world of electronic measurements. This enables the reader to understand the basic theory of signals and systems, relate it to measured results, and apply it when creating new designs.
