FOURIER ANALYSIS AND ITS APPLICATIONS

The purpose of this work is to explain how to apply the Fourier Analysis tool with Excel software in real data processing operations. Fourier Analysis is the most sophisticated Data Analysis tool in Excel. In fact, it is a form of direct Fourier Transform (FFT or Fast Fourier Transform).It is one of the most relevant tools for practical applications in science and engineering. The work deals with one of its most effective algorithms, the FFT and its inverse. We will analyze in depth how to apply this analysis tool to perform complex operations in the frequency domain. The tool is also applicable in the time domain. After understanding some special techniques, you'll be able to use Fourier Analysis from a numerical point of view.The techniques used in science and engineering have gained considerable relevance in the film industry in films such as Titanic, Star Wars, The Matrix, etc.
