The course focuses on explaining basic terms used for the description and analysis of determined signals and systems (including filters) in continuous- and discrete-time. The graduate will acquire a basic overview of the issues and learn how to work with concepts, perform simple analysis of systems and signals, and interpret and discuss the results.

Study targets:

Become familiar with the basic concepts and learn how to use MATLAB for analysis and design of systems and for signal processing.

Course outlines:

1. Continuous- and discrete-time signals and systems. Cross-energy and correlation
2. LTI system representation in the time domain, convolution
3. Representation of LTI systems in the frequency domain, frequency response
4. Transfer function of continuous-time systems, poles and zeros, the relationship between time and frequency domain, ideal integrator and differentiator
5. Bode and Nyquist frequency plot, asymptotic Bode plot
6. Stability, feedback, gain and phase margins
7. Relationship between transfer function and state-space representation of LTI continuous-time systems, asymptotic and BIBO stability
8. Nonlinear systems and their linearization for small signals
9. Sampling and reconstruction of signals, representation in time and frequency domain
10. Methods for discretization of continuous-time systems
11. Introduction to analog filters, types and properties of approximations
