Knowledge of the high school level math and physics is required. Emphasis is placed on the knowledge of complex numbers and their application.

Lab exercises are mandatory for successfully passing this course and students have to obtain the required credits. For lab work and numerical exercise tests they can get 40 out of 100 points. The remaining 60 points can be obtained by successfully passing the final written examination.


The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

The aim of the course is to acquaint students with one-dimensional (1D) and two-dimensional (2D) signals and systems with continuous-time, signals and systems with discrete-time, and with impulse and digital signals and systems. It is also necessary to introduce the concept of 1D and 2D signal spectrum and emphasize its difference from the frequency response of 1D and 2D system. Consequently, the aim is to provide students with basic information about random signals and their impact on systems, introduce modulations and define description of the characteristics of communication systems.
On completion of the course, students are able to:
- define, describe and visualize continuous and discrete-time signals
- perform some operations with signals such as convolution, correlation, time shift, time scale
- define continuous and discrete-time systems and describe their properties (time invariance, linearity, causality, stability)
- work with transfer function, impulse and frequency response
- calculate a response of LTI system
- perform spectral analysis of signal using the Fourier series, Fourier transform, discrete-time Fourier transform, discrete Fourier series, discrete Fourier transform and fast Fourier transform
- understand function of simple filters
- describe A/D and D/A conversion and prevent aliasing
- apply the Z transform
- describe differences between IIR and FIR systems
- connect partial system sections
- work with basic modulations
- mathematically describe stochastic processes
- estimate power spectral density
