+
+**Módulo Curricular**  
+_Creado con R2021b. Compatible con R2021b y versiones posteriores._  
+
+## Descripción ##
+Este módulo curricular enseña el análisis de Fourier utilizando [live scripts](https://www.mathworks.com/products/matlab/live-editor.html) y [aplicaciones de MATLAB®](https://www.mathworks.com/products/matlab/app-designer.html) interactivas. El módulo se enseña desde una perspectiva de procesamiento de señales, adecuada para un curso introductorio de señales y sistemas. En la primera lección, los estudiantes utilizan aplicaciones para visualizar series de Fourier y desarrollar intuición sobre el dominio de frecuencia. En lecciones posteriores, los estudiantes estudian series de Fourier complejas, transformadas de Fourier y transformadas de Fourier discretas. A medida que los estudiantes avanzan, pasan de utilizar aplicaciones a escribir su propio código para analizar señales. A lo largo del módulo, los estudiantes aplican técnicas de Fourier para analizar señales de audio grabadas.
+
+Cada tema incluye un laboratorio que aplica los conceptos enseñados en la lección. Las soluciones están disponibles a solicitud del instructor. Si desea solicitar soluciones o tiene alguna pregunta, comuníquese con el <a href="mailto:[email protected]">equipo de enseñanza en línea de MathWorks.</a>
+
+Comience con el módulo curricular de Análisis de Fourier descargando y descomprimiendo el repositorio. Luego, haga doble clic en el archivo .prj del proyecto dentro de MATLAB. A partir de ahí, puede seguir las instrucciones de la página de inicio para comenzar con los ejemplos y laboratorios.
