Module contents

Lecture:
- Properties of signals & LTI systems, plus mathematical basics (test signals, complex-exp, convolution)
- Display and analysis of periodic signals (Fourier series and spectrum)
- Fourier transform and properties
- Sampling and reconstruction of signals (sampling theorem, aliasing)
- Display of time-discrete signals (DFT, spectrum)
=====
- Various representations for LTI systems:
  Differential equation, block diagram, frequency response, impulse response, ...
- Relationships between the different representations and physical properties of 1st and 2nd order systems (LPF, HPF and BPF)
- Simulations and calculations in time (convolution with impulse response) and frequency domain (body diagrams & filtering)

Laboratory:

Exams

Description Type Form Scope Grade Weighting
Graded assignments during teaching semester       evaluation 40%
End-of-semester exam written exam 90 min evaluation 60%

Remarks

The exam regulation during the "teaching semester" can be varied.
But the lecturer has to document and communicate the definitive evaluation form in a
module agreement during the first week of the study semester.

Legal basis

The module description is part of the legal basis in addition to the general academic regulations. It is binding. During the first week of the semester a written and communicated supplement can specify the module description in more detail.
