Consultation

There will be a consultation session together with German students on Thursday, 4th of August, during the 2. DS. The room will probably be Bar/106/H.

If possible, send your questions before the consultation to simon.friedrich@tu-dresden.de. 

The aim of the consultation is to answer questions, not to make a summary of the lecture.

 

Important

In principle, lectures and exercises will be conducted in person and the corresponding material will be periodically uploaded.

 

Goals

​This lecture is held in English and is mainly aimed at students in our Master program, who are not yet familiar enough with the German language. The content corresponds to the German lecture "Nachrichtentechnik".

 

Content

​​Lecture:

  • Signal description: sine signals, Dirac impulse, spectral representation, low pass signals, band pass signals
  • Linear time invariant systems
  • Analog modulation: amplitude modulation, frequency modulation
  • Sampling theorem: sampling theorem for low-pass signals, sampling theorem for band-pass signals, sampling kernels
  • Digital modulation: frequency shift keying, phase amplitude modulation
  • Stochastic signals: spectral properties, correlation, noise

Exercise:
Problems and examples related to Fourier transform, analytical signals, linear time invariant systems, simple AM and FM transceivers, sampling and interpolation filters, digital modulation schemes and stochastic systems.​

 

Prerequisite
