Abstract:

Methods and algorithms for digital signal processing (DSP) are used everywhere in the modern world. Entertainment, medicine, defense, communications - all of these industries are now actively using DSP in real time mode. The current pace of development of electronic computing technology creates a good potential for further spread of the DSP in our life in the future.

Widespread usage of DSP algorithms and devices are makes the leading technical universities pay enough attention to the quality of courses in this discipline. The most significant indicator of the educational program is the level of students’ practical skills.

This article describes the method of DSP learning on example of working with audio signals. This approach allows students to evaluate the results of processing, not only on graphics, but also by ear. Real-time simulation system consists of high-tech DSP target board produced by Texas Instruments and PXI-platform developed by National Instruments. The interaction of these devices ensures the flexibility of the toolkit and provides the depth of practical skills gained by students. The software for the simulation system is developed by authors, but it presented as a reference design for students. Students use the developed reference software in their laboratory work, study the existing code and add missed fragments.

In this paper, the authors describe the methodology of the practical DSP-course, including lesson’s plan, description of the hardware and software toolkit in details, simulation signal methods and algorithms, the results of application learning method in high school. The simulation signal methods are developed in the framework of Project #2.7782.2017/BC with financial help of Russian Federal Ministry of Education.
