Exemplarische inhaltliche Operationalisierung

The following subjects can be presented quickly assuming students have had prior exposure to discrete-time systems:
  • Signals, Systems and Digital Signal Processing
  • Discrete-Time Linear Time-Invariant Systems
  • Ideal Sampling and Reconstruction
  • Fourier-Transform of Discrete-Time Signals
  • The z-Transform
The follwoing subjects should be presented in depth:
  •  Discrete Fourier-Transform
Design of Digital Filters
Random Signals
Advanced Sampling Techniques

The course should be complemented with selected topics from the following advanced subjects:
  • Optimum Linear Filters
  • Spectrum Estimation
  • Adaptive Filters
The theory should be illustrated and put into practise by MATLAB  code of the presented methods and algorithms
