In this thesis, the design and implementation of a universal board for audio signal processing is presented. The idea arises from the need for a device that enables acquisition, reconstruction, and intermediate processing of signals according to user requirements. The project developed from laboratory exercises in the course \textit{Discrete Signals and Systems}, where the opportunity emerged to connect theoretical knowledge with practical application.
In the design process, various approaches to programming and implementing digital filters were examined, including fundamental design methods that allow efficient execution on microcontrollers. Special attention was given to modularity and the possibility of using the board in different educational contexts.
The outcome of the work is a functional prototype of the board, which allows easy integration into a laboratory environment while also providing a platform for extensions and upgrades. The development process combines theoretical understanding with practical testing, giving students better insight into the operation of digital signal processing.
The conclusion of the thesis confirms that the proposed solution is successful and useful in the educational process. The board represents a tool that can help future generations of students better understand and practically apply methods of digital signal processing.
