Electrical Engineering, Media and Information Technology Electrical Engineering, Media and Information Technology

In the Media Systems Lab, students conduct experiments from courses in communications engineering and telecommunications, electrical engineering, and digital signal processing—with practical relevance to media systems.

In our modern Media Systems Lab, students enrolled in the media technology bachelor’s program conduct regular practical experiments in electrical engineering, communications engineering, and digital signal processing under the guidance of professors and technicians/ lab assistants. These laboratory experiments count toward exams and coursework and serve to intensify the lectures in the corresponding modules. In addition, the „Technical Project“ takes place here, in which students from the 1st and 2nd semesters implement microcontroller-based media technology devices, and general projects as well as elective courses are held as part of the new study focus “Media System Development.” The laboratory is also used for experimental research, e.g., in the research areas of “Sound Analysis and Design”, “Software-Defined Radio”, and “Mobile Communications” with projects in the fields of measurement technology, psychoacoustics, signal processing and analysis, and transmission technology.

The Media Systems Lab provides students with computer-based workstations, electronics workstations, and a fully equipped workshop for carrying out projects and bachelor's theses. The laboratory is located on the Finkenau Art and Media Campus, in rooms E51 and E55 (Building A, ground floor). Fourteen laboratory workstations equipped with PCs and digital and analog measuring devices are available for conducting hands-on laboratory exercises in the above-mentioned modules.

The laboratory exercises, organized by module, are structured as follows:

In Electrical Engineering 1 (ET1, 1st semester), basic measurement tasks are carried out on topics such as Ohm's law, Kirchhoff's laws, internal resistance of voltage sources, buffer operation with accumulators, capacitors, and magnetic circuits.

In Electrical Engineering 2 (ET2, 2nd semester), laboratory exercises are carried out in the alternating and three-phase current range, such as alternating current resistors, parallel resonant circuits, 1st and 2nd order filters, transformers, and three-phase circuits. The laboratory exercises are carried out on both discrete circuits and complex devices from the context of media technology.

In the Communications Engineering module (NAT, 3rd semester), laboratory exercises are offered on the topics of spectra and transmission, signal sampling, amplitude modulation, frequency modulation, and transmission lines in high-frequency technology.

As part of the Digital Signal Processing lecture (DSIG, 4th semester), in addition to an introduction to Matlab, laboratory exercises are offered that deal with the sampling theorem, DFT/FFT, windowing and the leakage effect, time-frequency representation, discrete convolution, difference equations, the z-transfer function, and the design of digital filters (IIR/FIR filters).

The course Communications Engineering/Telecommunications (NT, 5th semester) covers topics such as digital filters, digital signal processing, communications engineering, channel and source coding, encryption, and telecommunications. The aim is to provide students with a broad knowledge of systems relevant to the production and distribution of digital content, enabling them to take technical responsibility for system decisions, e.g., relating to procurement, system integration, and management.
