Lecture "Advanced Digital Signal Processing"


Basic Information

Lecture overview  
  Lecturers:   Gerhard Schmidt (lecture) and Owe Wisch (exercise)  
  Room:   Online (via zoom)  
  Language:   English  
  Target group:   Students in electrical engineering and computer engineering  
  Prerequisites:   Basic Knowlegde about signals and systems  

Students attending this lecture should be able to implement efficient and robust signal processing structures. Knowledge about moving from the analog to the digital domain and vice versa including the involved effects (and trap doors) should be acquired. Also differences (advantages and disadvantages) between time and frequency domain approaches should be learnt.

Topic overview:

  • Digital processing of continuous-time signals
  • Efficient FIR structures
  • DFT and FFT
  • Digital filters (FIR filters/IIR filters)
  • Multirate digital signal processing
