Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

E613 Electrical Engineering, Bachelor, ASPO 01.10.2005 , semester 6, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
75 class hours (= 56.25 clock hours) over a 15-week period.
The total student study time is 180 hours (equivalent to 6 ECTS credits).
There are therefore 123.75 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
E517 Optical Communications Systems
E518 High-Frequency Engineering

Learning outcomes:
After successfully completing this combined lecture and laboratory course, students will have a deeper understanding of high-frequency engineering. They will be able to perform computational analyses and experimental verifications on analogue and digital signal transmission systems. They will also be familiar with current applications of fixed-line and wireless-based transmission techniques and the latest transmission standards.
