Lecture "Digital Audio Effects"

Basic Information

Lecturers:   Klaus Linhard  (lecture and exercise)
Room:   Builing F, room F-SR-II (in the first week), building F, room F-SR-III (in the second week), and PC lab in building B (in the second week).
Language:   English
Target group:   Students in electrical engineering and computer engineering
Prerequisites:   Previous knowledge about digital signal processing and linear systems. Some experience with MATLAB is useful, but not mandatory.

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.

    • Difference equations
    • Linear systems
  • Frequency-domain processing - summary
    • Discrete Fourier transform
    • Fast convolution
    • Transfer functions and spectra
  • Introduction to MATLAB and motivation

New Lecture - Fundamentals of Acoustics

Starting this winter term the DSS group offers a new lecture entiteled "Fundamentals of Acoustcs". The lecture is given by Dr. Jan Abshagen (see picture). It will be a 3+1 lecture which takes place once a week. The lecture will cover the following topics:

  • fundamentals of vibrations,
  • theory of sound fields,
  • sound and systems,
  • transducers,
  • sound-structure interaction,
  • ship acoustics,
  • ...
