Digital Technology

Module name (EN):
Name of module in study programme. It should be precise and clear.
Digital Technology
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Computer Science and Communication Systems, Bachelor, ASPO 01.10.2014
Module code: KI370
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
4V (4 hours per week)
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
Semester: 3
Mandatory course: yes
Language of instruction:
Written exam 90 min.

[updated 06.07.2021]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

DFBI-343 (P610-0196) Computer Science and Web Engineering, Bachelor, ASPO 01.10.2018 , semester 6, optional course
KI370 (P200-0006) Computer Science and Communication Systems, Bachelor, ASPO 01.10.2014 , semester 3, mandatory course
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).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 120 hours (equivalent to 4 ECTS credits).
There are therefore 75 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
Recommended as prerequisite for:
KI440 Computer architecture
KI460 Microprocessor Systems
KI608 Semiconductor Technology and Production
KI653 Practical Circuit Design
KI698 Measurements and Simulations in Communications Engineering
