| || ||To learn and understand basic theory of signals and linear systems with
continuous and discrete time. To introduce to random signals. The
emphasis of the course is on spectral analysis and linear filtering - 2
basic building blocks of modern communication systems.|
| || ||Continuous and discrete time signals and systems. Spectral analysis in
continuous time - Fourier series and Fourier transform. Systems with
continuous time. Sampling and reconstruction. Discrete-time signals and
their frequency analysis: Discrete Fourier series and Discrete-time
Fourier transform. Discrete systems. Two-dimensional signals and
systems. Random signals.|
|Knowledge and skills required for the course:|
| || ||basic maths and statistics|
|Subject specific learning outcomes and competences:|
| || ||Students will learn and understand basis of description and
analysis of discrete and continuous-time signals and systems. They will
also obtain practical skills in analysis and filtering in MATLAB/Octave.|
|Generic learning outcomes and competences:|
| || ||Students will deepen their knowledge in mathematics and statistics and
apply it on real problems of signal processing. |

- participation in numerical exercises is not checked, but tests are conducted in them, each worth 2 points.
- Groups in numerical exercises are organized according to
inscription into schedule frames.
- Replacing missed exercises (and obtaining the points) is possible by (1) attending the exercise and the test with another group, (2) solving all tasks in given assignment and presenting them to the tutor, (3) examination by the tutor or course responsible after an appointment. Options (2) and (3) are valid max. 14 days after the missed exercises, not retroactively at the end of the course.

- 6 tests in numerical exercises, each 2 pts, total 12 pts.
- half-semester exam, written materials, computers and calculators prohibited, 25 pts.
- submission of project report - 12 pts.
- final exam - 51 pts., written materials, computers and calculators prohibited, list of basic equations will be at your disposal. The minimal number of points which can be obtained from the final
exam is 17. Otherwise, no points will be assigned to the student.
