Course detail
Experimental Modeling and Signal Processing
FSI-LES Acad. year: 2025/2026 Summer semester
In the subject, students will learn about the design of the experiment, the evaluation of the measured data into basic characteristics. Furthermore, with data processing using Fourier transformation, spectrogram and usability of these dependencies for practice. Sensitivity analysis and the basics of uncertainty in experimental modeling will also be part of the curriculum.

Entry knowledge
Basics of work in Python (Matlab), basics of dynamics and statistics.
Rules for evaluation and completion of the course
The course will end with the defense of individual projects and the examination of basic knowledge of the subject matter covered.
Participation in exercises is mandatory and controlled.
A rare non-participation in the exercises will lead to the assignment of substitute assignments.
Aims
The aim of the course is to introduce students to the design of an experiment and the evaluation of measured data. By processing measured data using Fourier transform, spectrogram. Also with signal filtering, basics of measurement uncertainty evaluation and sensitivity analysis.
