This volume aims to enhance the algorithms for acousto-optic correlative and spectral signal processing and extend their applications. The text assumes a basic familiarity with optical methods of information processing.
This book presents fundamentals and the latest techniques of electrical spectrum analysis. It focuses on instruments and techniques used on spectrum and network analysis, rather than theory. The book covers the use of spectrum analyzers, tracking generators, and network analyzers. Filled with practical examples, the book presents techniques that are widely used in signal processing and communications applications, yet are difficult to find in most literature. - Presents numerous practical examples, including actual spectrum analyzer circuits - Instruction on how to use spectrum analyzers, tracking generators, and network analyzers - End-of-chapter questions, which make the book suitable as a college-level text earthquakes
This book covers the theory and practice of spectrum and network measurements in electronic systems. Areas covered include: decibels, Fourier analysis, FFT and swept analyzers, modulated signals, signal distortion, noise, pulsed waveforms, averaging and filtering, transmission lines and measurement connection techniques, two-port network theory, network analyzers, and instrument performance and specifications. Noble Publishing has reprinted the 1993 volume (from Prentice Hall) as a "classic" in the field. Witte works for Agilent Rechnologies. c. Book News Inc.

Designed for electrical engineers working in the design, test and service of circuits/systems in the 0 to 500 MHz frequency range, this guide relates the theoretical background to real-world, practical measurement.
This report describes several efficient techniques that use a digital computer to measure the spectrum of a time function. The time function forms the input to a group of linear difference equations that are solved by the computer. Each member of this group of equations passes frequencies over a different narrowband interval of the frequency range being analyzed, and the squared and integrated equation outputs provide an estimate of the spectrum. Truncation of coefficients to the length of the computer word may result in unstable difference equations, and a special form of these equations has been developed that is insensitive to coefficient truncation. The equation form has also been chosen so that a minimum of computation is required in the solutions.
