Highschool Students Visiting the DSS Department

On Wednesday the 20th of June,  several highschool students of the first senior classes of the Isarnwohld School Gettorf visited the DSS department. Therefore, Prof. Schmidt gave a talk about possible professions for electrical engineers (especially with focus on signal processing) at the Isarnwohld School two days before. So the highschool students could think about the addressed topics and ...
