Basic Information

 
 
Lab overview  
  Lecturers:   Gerhard Schmidt, Alexej Namenas, Anton Namenas, and Christin Bald  
  Room:   -  
  Language:   German  
  Target group:   Students in electrical engineering and computer engineering  
  Prerequisites:   Signals and systems I  
  Registration procedure:  

If you want to sign up for this laboratory, you need to register with the following information in the registration form

  • surname, first name,
  • (stu) e-mail address,
  • matriculation number,

Please note, that the registration period starts the 07.09.2020 at 00:01 am and ends the 28.10.2020 at 23:59 am. All applications before and after this registration period will not be taken into account.

Registration will be possible within the before mentioned time by sending a mail with your name and matriculation number to This email address is being protected from spambots. You need JavaScript enabled to view it.

The registration is binding. A deregistration is possible by sending a mail with your name and matriculation number to This email address is being protected from spambots. You need JavaScript enabled to view it. until Friday, 23.10.2020 at 12:00 am. All later cancellations of registration will be considered as having failed the lab.

Requirements, rules and commitments will be announced at the first experiment (attendance is mandatory).

The lab Systemtheory will take place with an online support.

The lab will be executed with Octave (and not with Matlab) this year.

 
  Time:  

The first experiment takes place on the 04.11.2020 via BigBlueButton. The corresponding documents and the link for attending the BigBlueButton meeting will be distributed shortly before the first experiment since there is no preliminary work required. The schedule of all experiments can be found in the list below.
