Genre: Technology & Engineering

This book presents recent advances in DSP to simplify, or increase the computational speed of, common signal processing operations. The topics describe clever DSP tricks of the trade not covered in conventional DSP textbooks. This material is practical, real-world, DSP tips and tricks as opposed to the traditional highly-specialized, math-intensive, research subjects directed at industry researchers and university professors. This book goes well beyond the standard DSP fundamentals textbook and presents new, but tried-and-true, clever implementations of digital filter design, spectrum analysis, signal generation, high-speed function approximation, and various other DSP functions.

Release Date: 2016-10-21
Genre: Technology & Engineering

Field Programmable Gate Arrays (FPGAs) sind relativ komplexe programmierbare Logikbausteine. Mithilfe von FPGAs können mittlerweile jedoch auch Maker und Elektronikbastler eigene Chips entwerfen. Wie das geht, zeigt Ihnen dieses Buch. Zunächst wird erklärt, was FPGAs sind und wie sie funktionieren. Es folgt eine Einführung in die Hardwarebeschreibungssprache VHDL, die für die Projekte in diesem Buch verwendet wird. Danach wird Schritt für Schritt anhand zunächst ganz einfacher Beispiele erläutert, wie man eine Schaltung mithilfe eines FPGA realisiert. Im weiteren Verlauf werden die Schaltungen anspruchsvoller. Den Abschluss bildet ein Projekt, bei dem das Spiel »Pong« in Hardware realisiert wird. Die Anzeige erfolgt auf einem RGB-LED-Matrix-Display, dessen Ansteuerung per FPGA im Detail beschrieben wird. Die Projekte im Buch werden auf Basis kostenlos verfügbarer FPGA-Entwicklungsumgebungen der Hersteller Altera, Lattice, Microsemi und Xilinx sowie günstiger FPGA-Boards konkret umgesetzt. Dabei wird auf die Übertragbarkeit auf andere Systeme geachtet. Die verwendeten Entwicklungsumgebungen und FPGA-Boards werden außerdem kurz vorgestellt. Cord Elias konzentriert sich primär auf die Vermittlung von Fähigkeiten zum selbstständigen Umgang mit FPGAs. Er nimmt die Leserinnen und Leser an die Hand und leitet sie sicher durch eine Vielzahl von Details. Dass der Spaß dabei nicht zu kurz kommt, versteht sich von selbst. Der Quellcode zu allen Design-Beispielen steht zum Download bereit.

What are the relations between continuous-time and discrete-time/sampled-data systems, signals, and their spectra? How can digital systems be designed to replace existing analog systems? What is the reason for having so many transforms, and how do you know which one to use? What do s and z really means and how are they related? How can you use the fast Fourier transform (FFT) and other digital signal processing (DSP) algorithms to successfully process sampled signals? Inside, you'll find the answers to these and other fundamental questions on DSP. You'll gain a solid understanding of the key principles that will help you compare, select, and properly use existing DSP algorithms for an application. You'll also learn how to create original working algorithms or conceptual insights, design frequency-selective and optimal digital filters, participate in DSP research, and select or construct appropriate hardware implementations. Key Features * MATLAB graphics are integrated throughout the text to help clarify DSP concepts. Complete numerical examples clearly illustrate the practical uses of DSP. * Uniquely detailed coverage of fundamental DSP principles provides the rationales behind definitions, algorithms, and transform properties. * Practical real-world examples combined with a student-friendly writing style enhance the material. * Unexpected results and thought-provoking questions are provided to further spark reader interest. * Over 525 end-of-chapter problems are included, with complete solutions available to the instructor (168 are MATLAB-oriented).

Biomedical Signal Processing and Signal Modeling

ISBN: UOM:39015049532933
Release Date: 2001
Genre: Medical

A biomedical engineering perspective on the theory, methods, and applications of signal processing This book provides a unique framework for understanding signal processing of biomedical signals and what it tells us about signal sources and their behavior in response to perturbation. Using a modeling–based approach, the author shows how to perform signal processing by developing and manipulating a model of the signal source, providing a logical, coherent basis for recognizing signal types and for tackling the special challenges posed by biomedical signals–including the effects of noise on the signal, changes in basic properties, or the fact that these signals contain large stochastic components and may even be fractal or chaotic. Each chapter begins with a detailed biomedical example, illustrating the methods under discussion and highlighting the interconnection between the theoretical concepts and applications. The author has enlisted experts from numerous subspecialties in biomedical engineering to help develop these examples and has made most examples available as Matlab or Simulink files via anonymous ftp. Without the need for a background in electrical engineering, readers will become acquainted with proven techniques for analyzing biomedical signals and learn how to choose the appropriate method for a given application. An Instructor′s Manual presenting detailed solutions to all the problems in the book is available from the author.
