Innledning
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 the same analytic methods apply. Reconstruction of medical images will be used as practical application.
Anbefalte forkunnskaper
Signal Processing or knowledge of the Fourier and Laplace transforms. Some knowledge of Matlab progamming.
Forkunnskapskrav
No formal requirements over and above the admission requirements.
Læringsutbytte
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 and analogue systems
- Filtering
- Detection techniques, correlation and deconvolution
- Reconstruction of images from measured data by inverse methods
Skills
The student will know how to:
- Describe digital signals and systems mathematically in the time domain, the frequency domain and the Z-domain
- Describe digital images mathematically in real space and K-space
- Describe linear time invariant systems using difference equations, impulse responses, point spread functions and transfer functions
- Analyze time discrete systems in the frequency domain and discrete images in K- space
- Use analog filters and the digitized versions of analog filters: FIR and IIR
- Apply post processing of images for filtering
- Apply inverse methods for image reconstruction from measured data
General competence
The student will have general competence on:
- Spectrums, impulse responses, point spread functions, frequency responses, K- space, correlation, convolution and modulation
- Fourier-series (FS), Fourier transform (FT).
- Sampling, reconstruction and aliasing
- Implementation of DSP-filters and inverse methods on a computer.
