  Prerequisites:   Signals and systems I,II  
  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,
  • e-mail address,
  • matriculation number,

Please note, that the registration period starts the 12.03.2019 at 13:00 am and ends the 01.04.2019 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 under the following subsite - Lab Registration.

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 Monday, 25.03.2019 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 preliminary meeting (attendance is mandatory).

 
  Time:  

The first experiment takes place on the 11.04.2019 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 Thursday: 14:00 - 18:00 h
