Beschreibung

An ideal resource for students, industrial engineers, and researchers, Signal Processing with Free Software Practical Experiments presents practical experiments in signal processing using free software. The text introduces elementary signals through elementary waveform, signal storage files and elementary operations on signals and then presents the first tools to signal analysis such as temporal and frequency characteristics leading to Time-frequency analysis. Non-parametric spectral analysis is also discussed as well as signal processing through sampling, resampling, quantification, and analog and digital filtering. Table of Contents: 1. Generation of Elementary Signals. Generation of Elementary Waveform. - Elementary Operations on the Signals. - Format of Signal Storage Files. 2. First tools of Signal Analysis. Measurement of Temporal and Frequency Characteristics of a Signal. Time-Frequency Analysis of a Signal. 3. Non-parametric Spectral Analysis. 4. Signal Processing. Sampling. - Resampling. - Quantification. - "Analog" Filtering. Digital Filtering

Preface

This book is based on the teaching documents used in the Physical Measurements Department at the University Institute of Technology in Saint-Nazaire, France, and is aimed at cooperative work/study engineering schools. It is not intended to provide a full grounding in signal processing for which readers should consult the reference works cited in the bibliography.

I wish to thank my colleagues (M. Belkadi, T. Hairie, F. Poyer, H. Menana, J.-C. Olivier, B. Velay and Z. Shi) who have participated in this teaching activity and helped me to improve the quality of the content, and my students (in particular, A. Baudry, A. Bouvet, F. Gibon, R. Monnier and S. Vaillant) who, through their questions, have helped me to clarify and add certain exercises.

Introduction

The aim of these practical exercises is to demonstrate some of the possibilities of practical implementation of signal processing techniques. To do this, we will use free software applications, including SOX, Audacity and Visual Analyser, focusing on their uses in real situations.
