Introduction
Signal processing defines the mathematical tools used to analyze, model and operate on measured data from physical signals and their sources. In digital signal processing (DSP) the following topics are lectured: the different domains for describing discrete signals and linear time invariant systems, digital filters and frequency analysis. Images are two-dimensional signals and similar analytic methods apply.
Recommended preliminary courses
Signal Processing or knowledge of the Fourier and Laplace transforms. Some knowledge of Matlab progamming.
Required preliminary courses
No formal requirements over and above the admission requirements.
Learning outcomes
On completion of this course, the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
Knowledge
The course will give the students in depth knowledge on the following topics
- Sampling, digitalization and reconstruction.
- How to obtain the signal spectrum of digital and analog signals
- How to obtain the frequency response of digital systems
- Methods of filtering discrete signals
- Digital image formats
Skills
The student will know how to:
- Describe digital signals and systems mathematically in the time domain
- Describe discrete signals and systems in the frequency domain and the Z-domain
- Describe digital images mathematically in real space and frequency space
- Describe linear time invariant systems using difference equations, impulse responses, and transfer functions
- Analyze time discrete systems in the frequency domain
- Use discrete filters and the digitized versions of analog filters: FIR and IIR
- Apply post processing of images for filtering, noise reduction, edge detection and presentation.
General competence
The student will have general competence on:
- Frequency spectrums, impulse responses, frequency responses, convolution and modulation
- Fourier-series (FS), Fourier transform (FT).
- Sampling, reconstruction and aliasing
- Implementation of DSP-filters
- Improving image presentation

Assessment
Exam autumn 2021 due to Covid-19:
Individual digital home exam, 3 hours and 30 min to upload/scan.
The exam grade can be appealed.
New/postponed exam
In case of failed exam or legal absence, the student may apply for a new or postponed exam. New or postponed exams are offered within a reasonable time span following the regular exam. The student is responsible for applying for a new/postponed exam within the time limits set by OsloMet. The Regulations for new or postponed examinations are available in Regulations relating to studies and examinations at OsloMet.
In the event of a postponed examination in this course the exam may be held as an oral exam. Oral exams cannot be appealed.
[Exam earlier:]
Individual written exam, 3 hours.
The exam grade can be appealed.
New/postponed exam

Permitted exam materials and equipment
All written material, but no communication will be allowed.
Grading scale
For the final assessment a grading scale from A to E is used, where A denotes the highest and E the lowest pass grade, and F denotes a fail.
Examiners
Two internal examiners. External examiner is used periodically.
