Fourier Analysis

Curriculum Module
Created with R2021b. Compatible with R2021b and later releases.

Description

This curriculum module teaches Fourier analysis using interactive live scripts and MATLAB® apps. The 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.

Each topic includes a lab that applies the concepts taught in the lesson. The solutions are available upon instructor request. If you would like to request solutions or have a question, contact the MathWorks online teaching team.

Get started with the Fourier Analysis curriculum module by downloading and unzipping the repository. Then, double-click the project .prj file inside MATLAB. From there, you can follow the landing page instructions to get started with the examples and labs.
