to the E-Mail adress This email address is being protected from spambots. You need JavaScript enabled to view it.. Please note, that the registration period starts the 28.03.2018 at 8:00 am and ends the 03.04.2018 at 12:00 am. All applications before and after this registration period, will not be taken into account. Wishes concerning the weekday and the group partners of the lab will be accepted and tried to be considered, but can not be guaranteed.   

The announcement of the students successfully registered to the lab, will be until the 06.04.2018 6:00 pm or earlier, if the course is already occupied. A list of all registered students, the group assignment and the day of their lab will be announced here in the section Details.

The first experiment takes place on the 11.04.2018 and the 12.04.2018 in the PC Lab of Building B. The corresponding documents will be distributed at the beginning of this first experiment since there is no preliminary work required. The schedule of all experiments and the group assignment can be found in the list below.

  • On Wednesdays: 14:00 - 18:00 h
  • On Thursday: 14:00 - 18:00 h

Note: The content of the lab will be revised this semester step by step. Therefore some lab content could be possibly changed.
