    7. Objectives, learning outcomes and obtained knowledge
    Basic goal of the „Infocommunication” subject is to present specific terms, procedures, problems and solutions
    used in telecommunications. The subject strives to give solid basis of the most important terms and
    procedures to support further studies of related orientations. For all future electroengineers the subject provides basic knowledge for the forthcoming studies,
    whatever specialization is chosen by the student. Both the lectures and the seminars aim to teach the students so that they not only understand
    but are able to apply the known methods, procedures, e.t.c., on their own. On the other hand,
    it is also important to point out the trends and innovations of the infocommunication technologies so
    that the students could be able understand them with a little individual effort.

    9. Method of instruction
    Theoretical basis given on lectures, 3 hours/week. Practical examples and numerical problems are discussed on 
    seminars, 2 hours/week.
    10. Assessment
    One midterm test on the 11th week.
    Exam: same form as the midterm test, i.e. students have to solve 3 numerical examples, 
    write one essay on topic discussed on the lecture and give short explanation of 10 keywords.
    11. Recaps
    Those who failed the midterm test, have to write a complementary test on the 13th week or (and if failed again)
    on the 1st exam (in the latter case from the whole topics). Signature given to those who passed one of the tests. As commonly, those who fail the exam have right for one repeated exam and one "dean's chance".
    12. Consultations
    Consultations from the material of lectures and seminars given separately by the lecturer and 
    the seminar leader on the students' request.
