Signal classification: Peridical signals, non-periodical signals, causal and non-causal signals, signals in the continuous and discrete time. Basic signal characteristics: mean value, power, energy, correlation function. Spectral representation of signals: Fourier series, Fourier transform, DTFT, DFT. Selected signals examples: Rectangular pulse, Diraque pulse, unity step pulse. Bandpass signals: Hilbert transform, envelope, phase, frequency, complex envelope, bandpass signal sampling. Continuous time systems: Classification, LS systems, frequency domain and time domain representation, stability and causality, output signal characteristics. Discrete time systems: Classification, difference eqations, Z. transform, LS systems characteristics in the time and frequency domain. Stability and causality, output signal characteristics. Random signals: Random signals description and characteristics, staionary and ergodic signals, cyclostationary components of the random signals, autocorelation function and the power spectra, random signals in LTI systems.

Learning outcomes
|
The aim of the subject is to provide students with teoretical backgrounds of signals and systems needed for the further study of signal processing in communication and control. The subject links to basic knowledge of signals, electronic circuits and modulations gained during the bachalor study.
Student will get basics in theory of the determined and random signals and in linear systems both in the continuous and discrete time needed for the further study of the signal transfer and processing in communication and control.
