Prerequisites
ZD_06 Math and Physics
In general, the secondary-school level of knowledge from the area of mathematics and physics is required. It is also assumed that student can compute the derivative and integral of a function, modify equations with logarithms, complex numbers and trigonometric functions, solve linear equations. A general knowledge of programming and computer skills are welcomed.
Course Enrolment Limitations

Course objectives
To give to students basic information about one-dimensional signals and systems with continuous and discrete time and to explain the concept of frequency spectrum of signal, frequency characteristics of system and the principle of analogue-to-digital conversion and signal filtration.
Learning outcomes
Student, who passed the course, is able:
- to distinguish basic kinds of signals, to perform basic mathematical operations with them,
- to compute and draw frequency spectra of periodic signals,
- to list main characteristics of systems, define their basic parameters,
- to classify frequency filters, to explain principle of signal filtration,
- to list and explain principle of basic analog modulations,
- to compare and highlight differences between continuous-time signals and discrete-time signals,
- to explain principle of signal sampling and reconstruction, to describe functions of the individual blocks of A/D and D/A convertors,
- to apply the required knowledge about the principle of A/D and D/A conversion to specific examples related to the digitalization of audio signals,
- to describe the Fourier transform using mathematical equation and explain its meaning,
- to define and calculate basic characteristics of a random signal,
- to calculate power spectral density of signal.

Teaching methods
Teaching methods comprehend lectures and computer exercises. During the lectures, the theory is explained with the aid of MATLAB-SIMULINK models and solution of typical examples. The MATLAB software is used for computer exercises too. They are focused on solving practical problems from the field of signal processing.
Assessment methods
The final grade depends on total sum of points obtained during the computer exercises and for the written exam of the course. Student can get:
- up to 30 points for all computer exercises, during them student obtain points for correctly processed tasks and for the correctly answered questions of the final test.
- up to 70 points for compulsory exam, which has a written form and only students who passed ¾ of computer exercises, at least, and the final test can try to pass the exam. If the examiner has a problem with the evaluation of the written exam, he/she can put supplement oral questions to the student.
50 points is the minimum needed to successfully pass the course.
