News
The lecture will be given in presence (Room C-SR-I). We will start with the lecture on Thursday, 14.04.2022. In the first week, there will be no excersise (also in the second week, due to "Karfreitag").
The results of the exam from 18.03.2022 are now online in the QIS system! The exam review will take place on 01.04.2022, more detailed information will follow shortly by mail.

A new podcast on our research on signal processing for underwater applications is online now. Liv Schnoor (previously Presser) interviewed Karoline Gussow, Bastian Kaulen, Gerhard Schmidt, and Owe Wisch on our latest research. It was really fun for us and the time (about on hour) was over really soon.
