tailieunhanh - FOURIER TRANSFORM APPLICATIONS

During the preparation of this book, we found that almost all the textbooks on signal analysis have a section devoted to the Fourier transform theory. The Fourier transform is a mathematical operation with many applications in physics, and engineering that express a mathematical function of time as a function of frequency, known as its frequency spectrum; Fourier's theorem guarantees that this can always be done. | FOURIER TRANSFORM APPLICATIONS Edited by Salih Mohammed Salih Fourier Transform Applications Edited by Salih Mohammed Salih Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
