There will be no exercise in the first week of the semester (09.04.2019). The exercise will start the week after on the 16.04.2019.

Starting this semester exam procedure for Signals and Systems I will be adapted slightly. The notes on the exam execution and rules will be shortened. Instead of reading out the whole exam problems there will be 10 minutes of additional reading time. Please note that during this reading time no writing will be allowed.

Exam Results and Exam Inspection:

The results of the winter semester's exam of 05.03.2019 are online in the QIS-system. Please note the date of the exam inspection:

Date: Friday, 12.04.2019
Time: 9:00 h - 10:00 h
Room: Library of the DSS-group (D-037 A)

Please note that any information regarding your exam, including achieved points and "how close" you are to passing, can only be given out during an official exam inspection. Your grades will always be available through the QIS-system as soon as possible.

Saturday Morning Physics 2018

The DSS team was invited to participate in the last of the "Saturday Morning Physics" (SMP) events in 2018. On December 8th, a Saturday of course, Thorben Kaak, Gerhard Schmidt, and Owe Wisch gave a talk on underwater signal processing. Pupils from all around Schleswig-Holstein were quite interested, especially in the basics of SONAR systems.
