Available in PDF, EPUB and Kindle. Book excerpt: La transformation de Fourier (Vol. IV et VI) est un outil très précieux en traitement des signaux, elle intervient en particulier dans l'analyse spectrale, qui en est une application fondamentale. Avec les méthodes classiques, le calcul de cette transforma- tion par voie numérique nécessite un temps de calcul prohibitif. L'algorithme de cal- cul rapide - connu sous le nom de transformation de Fourier rapide (en anglais : Fast Fourier Transform ou FFT) — a permis de réduire considérablement ce temps de calcul. Plusieurs méthodes, en particulier un certain nombre de traitements non linéaires déve- loppés préalablement sur le plan théorique, ont pu être appliquées avec succès grâce à cet algorithme. Le traitement numérique des signaux bidimensionnels — c'est-à-dire des images — a également bénéficié très fortement de cet algorithme, dont l'introduction dans cette discipline a constitué un tournant. Les progrès technologiques continus dans le domaine des circuits intégrés, surtout à large échelle, ont permis la réduction des prix et des dimensions des systèmes numéri- ques, tout en permettant la conception de circuits de plus en plus complexes. C'est ainsi qu'on est passé des ordinateurs aux mini-ordinateurs, dont l'architecture peut être conçue de manière à optimiser les traitements numériques. Actuellement, des organes périphériques spécialisés, de complexité croissante, se développent pour augmenter la vitesse tout en maintenant un coût économiquement admissible. Le développement relativement récent des microprocesseurs a permis une miniaturisation plus grande tout en gardant l'avantage de la souplesse. Parallèlement, des circuits intégrés spécialisés, moins souples mais rapides, ont été développés permettant l'élaboration de systèmes de traitements numériques complexes qui travaillent en temps réel. Aujourd'hui, une gran- de partie des systèmes modernes de transmission de parole, de radar et de sonar sont entièrement numériques. Grâce aux progrès mentionnés précédemment, le traitement numérique de signaux est devenu, de nos jours, une discipline à part entière dont l'im- portance ne fait que croître. C'est pour les raisons citées ci-dessus que le volume XX s'insère dans le Traité d'Electricité, afin de couvrir le volet complémentaire du volume VI, tout en signalant les concepts similaires. Hormis quelques notions fondamentales sur la décomposition en série de Fourier — introduites dans le volume IV et développées dans le volume VI — la lecture du présent volume ne nécessite comme connaissances préalables, que les bases élémentaires de la théorie des probabilités, des fonctions complexes et du calcul matriciel.

Available in PDF, EPUB and Kindle. Book excerpt: L'ouvrage (niveau C) : Pour les formations universitaires de type EEA et celles d'ingénieurs en électronique et informatique industrielle, l'ouvrage apporte une présentation claire et synthétique des notions à la base du traitement du signal numérique. Après un résumé très consistant sur le traitement du signal analogique, l'exposé introduit progressivement les notions associées au traitement du signal numérique : échantillonnage, quantification, transformée de Fourier discrète, transformée en Z et filtrage numérique, pour arriver à la mise en œuvre pratique sur un processeur de traitement du signal (DSP). Afin de faciliter la compréhension et l'assimilation des notions essentielles, une grande place est accordée aux illustrations et aux exemples à travers des programmes écrits en langages Matlab(r), C ou assembleur. Un certain nombre de démonstrations constituent également un large éventail d'exercices corrigés utilisables à des fins d'entraînement.

Download or read book New Digital Signal Processing Methods written by Raoul R. Nigmatullin and published by Springer Nature. This book was released on 2020-05-23 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a manual on modern advanced statistical methods for signal processing. The objectives of signal processing are the analysis, synthesis, and modification of signals measured from different natural phenomena, including engineering applications as well. Often the measured signals are affected by noise, distortion and incompleteness, and this makes it difficult to extract significant signal information. The main topic of the book is the extraction of significant information from measured data, with the aim of reducing the data size while keeping the basic information/knowledge about the peculiarities and properties of the analyzed system; to this aim, advanced and recently developed methods in signal analysis and treatment are introduced and described in depth. More in details, the book covers the following new advanced topics (and the corresponding algorithms), including detailed descriptions and discussions: the Eigen-Coordinates (ECs) method, The statistics of the fractional moments, The quantitative "universal" label (QUL) and the universal distribution function for the relative fluctuations (UDFRF), the generalized Prony spectrum, the Non-orthogonal Amplitude Frequency Analysis of the Smoothed Signals (NAFASS), the discrete geometrical invariants (DGI) serving as the common platform for quantitative comparison of different random functions. Although advanced topics are discussed in signal analysis, each subject is introduced gradually, with the use of only the necessary mathematics, and avoiding unnecessary abstractions. Each chapter presents testing and verification examples on real data for each proposed method. In comparison with other books, here it is adopted a more practical approach with numerous real case studies.
