Mål:
The course introduces the ideas of modern communication technology. The course objectives are to answer some basic questions: What kinds of information need to be sent? How are they measured? How can they be transmitted or stored? What is the advantage of digital transmission? How do communication networks function? What natural laws govern information transmission? The course prepares the student to choose among more advanced offerings.
Competence objectives: Each student is expected to be able to decide the difficulty level of the problems encountered, compare this level to her/his own ability, and to identify and improve their abilities if insufficient.
Cognitive objectives: The objectives of the course are to provide the students with professional confidence so that they are able to make an informed choice of future electives within the areas of information transmission and communication engineering.
The student should have an overview of the basic problems and solutions that are encountered in the field, as well as an ability to analyze and describe information transmission systems of low to medium complexities.
