Undergraduate Lecture Notes in Physics,2192-4791Bibliographic Level Mode of Issuance: Monograph3-319-16984-X Includes bibliographical references and index.Introduction -- Fourier Series -- Continuous Fourier Transformation -- Window Functions -- Discrete Fourier Transformation -- Filter Effect in Digital Data Processing -- Data Streams and Fractional Delay -- Tomography: Back projection of Filtered Projections.This book is an introduction to Fourier Transformation with a focus on signal analysis, based on the first edition. It is well suited for undergraduate students in physics, mathematics, electronic engineering as well as for scientists in research and development. It gives illustrations and recommendations when using existing Fourier programs and thus helps to avoid frustrations. Moreover, it is entertaining and you will learn a lot unconsciously. Fourier series as well as continuous and discrete Fourier transformation are discussed with particular emphasis on window functions. Filter effects of digital data processing are illustrated. Two new chapters are devoted to modern applications. The first deals with data streams and fractional delays and the second with the back-projection of filtered projections in tomography. There are many figures and mostly easy to solve exercises with solutions.Undergraduate Lecture Notes in Physics,2192-4791PhysicsSignal processingImage processingSpeech processing systemsMathematical physicsMathematical Methods in Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19013Signal, Image and Speech Processinghttps://scigraph.springernature.com/ontologies/product-market-codes/T24051Mathematical Applications in the Physical Scienceshttps://scigraph.springernature.com/ontologies/product-market-codes/M13120Physics.Signal processing.Image processing.Speech processing systems.Mathematical physics.Mathematical Methods in Physics.Signal, Image and Speech Processing.Mathematical Applications in the Physical Sciences.515.723Butz Tilmanauthttp://id.loc.gov/vocabulary/relators/aut792295MiAaPQMiAaPQMiAaPQBOOK9910300409203321Fourier Transformation for Pedestrians1771579UNINA
