Researching and Modeling of Discrete Linear Time-Invariant Systems with Difference Equations in Matlab

The paper examines the opportunities for developing the skills and competencies of engineering students to understand the fundamental concepts embedded in digital signal processing. The Matlab-Simulink development software environment was used for research and teaching of Discrete Linear Time-Invariant (LTI) Systems through Difference Equations (DE), for which purpose a general engineering algorithm and a simulation model have been created, implementing the recursive Discrete LTI systems. The results of the conducted analytical and simulation researches are presented.
