Teaching methods
Summary
This course is intended primarily for Bc. degree students in VSB - Technical University of Ostrava on Faculty of electrical engineering and computer science.
In this course are took subjects of analysis of countinuous time signals and analysis of discrete time signals. Basic chracteristics of harmonic, periodic, energy and stochastic signals are studied. The students will know impulse amplitude modulation and code modulation.
The purpose of the course is to provide a common background for other study in control, communication, electronic circuits, filter design, digital signal processing.

Recommended literature:
Way of continuous check of knowledge in the course of semester
Verification of study:
Student must work out two laboratory works. The first one is related to the analysis of the discrete-time signal, the second one is related to the analysis of the discrete-time system. Student can receive up to 10 points for each of works. Maximum number of points student can gain through tests is 2 * 10 = 20 points.
Student has to elaborate two test. Student can acquire up to 10 points for each of them. Maximum number of points which student can gain through the tests is 2 * 10 = 20 points.
Student can gain up to 20 + 20 = 40 points from the laboratory excercices.
To pass the course student has to pass both the laboratory part of the course and the final exam. The final exam consists of writing part 0 - 50 points and oral part 0 -10 points. Student have to succeed in all parts of examination.
Conditions for credit:
Student must work out two laboratory works and two tests. To pass the laboratory part of the course student has to gain at least 20 points from the laboratory excercices.
