Subject aims expressed by acquired skills and competences

The purpose of the course Digital Signals and Systems is to provide a common background for digital signal processing and digital filter design. Student will master the analysis of both the discrete-time signal and discrete time LTIL system. The correlation analysis and spectral analysis of signal and system will be discussed. Laboratory work will be made in MATLAB and in MATLAB/Simulink toolbox environment.

Summary

The purpose of the course is to provide a common background for BS courses in control and communicastion. It is oriented in digital signal processing and digital filter design. The course Digital Signals and Systems introduces discrete-time and digital signals and systems. It is a subsequent course to the BS course Foundation of Signals and Systems which is devoted mainly to continuous-time signals and systems. The course introduces fhe following five major topics: 1. Fundamental concepts (causality, linearity, time-invariance, lumpedness and their applications) 2. Signal analysis (discrete-time Fourier transform, frequency spectrum and its computations) 3. System analysis (LTIL system analysis, the difference equations, z-transform) 4. Stabilities and their implications (filtering, frequency response, model reduction and memory circuits) 5. State variable equations and computer simulations (numerical methods, simulation means).

Way of continuous check of knowledge in the course of semester

Verification of study: Student must work out two laboratory works. The first one is related to the analysis of the discrete-time signal, the second one is related to the analysis of the discrete-time system. Student can receive up to 10 points for each of works. Maximum number of points student can gain through tests is 2 * 10 = 20 points. Student has to elaborate one test. Student can acquire up to 20 points for it. Student can gain up to 20 + 20 = 40 points from the laboratory excercices. To pass the course student has to pass both the laboratory part of the course and the final exam. the Final exam consists of writing part 0 - 50 points and oral part 0 -10 points. Student have to succeed in all parts of examination. Conditions for credit: Student must work out two presented laboratory works and one test. To pass the laboratory part of the course student has to gain at least 10 points from the laboratory excercices.
