Learning Outcomes

General competences

The student gets a modern approach of signal analysis combining functional analysis and mathematical statistics. The course entails on the one hand techniques to analyse a sampled signal form a statistical point of view and delivers the computational techniques to compute the solution and introduces on the other hand the theory of frames and wavelets to analyse signals in the time-frequency domain.

Grading

The final grade is composed based on the following categories:
Other Exam determines 100% of the final mark.

Within the Other Exam category, the following assignments need to be completed:

  • Examen andere with a relative weight of 1 which comprises 100% of the final mark.

Additional info regarding evaluation

The exam covers theory and exercises. The student defends his/her answers orally after a written preparation. The harmonic and wavelets part each account for 50% of the marks:

50%: Theory

20%: Exercises

30%: Group assignment (two tasks for each part per group. The marks on the project are kept for the second exam session).

The student needs to take part in all these evaluations to be able to pass the exam.

Allowed unsatisfactory mark
The supplementary Teaching and Examination Regulations of your faculty stipulate whether an allowed unsatisfactory mark for this programme unit is permitted.
