Compatible with R2024a and later releases._\n\n# Information\n\nThis curriculum module contains interactive [MATLAB® live scripts](https://www.mathworks.com/products/matlab/live-editor.html) and [MATLAB® apps](https://www.mathworks.com/products/matlab/app-designer.html)  that teaches fundamental concepts of fourier analysis.\n\n## Background\n\nThe module is taught from a signal processing perspective at a level suitable for an introductory signals and systems course. In the first lesson, students use apps to visualize Fourier series and build intuition about the frequency domain. In subsequent lessons, students study complex Fourier series, Fourier transforms, and discrete Fourier transforms. As students progress, they transition from utilizing apps to writing their own code to analyze signals. Throughout the module, students apply Fourier techniques to analyze recorded audio signals.\n\n\nThe instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the \u003cimg src=\"Images/image_0.png\" width=\"19\" alt=\"image_0.png\"\u003e Stop button in the **RUN** section of the **Live Editor** tab in the MATLAB Toolstrip.\n\n## Contact Us\n\nSolutions are available upon instructor request. Contact the [MathWorks teaching resources team](mailto:onlineteaching@mathworks.com) if you would like to request solutions, provide feedback, or if you have a question.\n\n\n## Prerequisites\n\nThis module assumes minimal MATLAB knowledge required for these scripts, but you could use [MATLAB Onramp](https://matlabacademy.mathworks.com/details/matlab-onramp/gettingstarted) as a resource to acquire familiarity with live scripts and MATLAB syntax.\n\n\n## Getting Started\n### Accessing the Module\n### **On MATLAB Online:**\n\nUse the [\u003cimg src=\"Images/image_1.png\" width=\"136\" alt=\"image_1.png\"\u003e](https://matlab.mathworks.com/open/github/v1?repo=MathWorks-Teaching-Resources/Fourier-Analysis\u0026project=fourier-analysis.prj\u0026file=README.mlx) link to download the module. You will be prompted to log in or create a MathWorks account. The project will be loaded, and you will see an app with several navigation options to get you started.\n\n### **On Desktop:**\n\nDownload or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double\\-click on [fourier\\-analysis.prj](https://matlab.mathworks.com/open/github/v1?repo=MathWorks-Teaching-Resources/Fourier-Analysis\u0026project=fourier-analysis.prj\u0026file=README.mlx). It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start. \n\n\nEnsure you have all the required products (listed below) installed.
