Summary |
---|
This subject belongs to the set of basic mathematical subjects of technical university studies. Student gets know the theory and use of the Laplace transform, Z-transform, Fourier series, Fourier and Window-Fourier transform, Wavelet transform in the continuous form and discrete form as well including algorithms, efficient implementations and applications for signal processing, e.g. time-frequency analysis, compression, filtering etc. |
Learning Outcomes of the Course Unit |
---|
Stundent ought to manage the theory and practise of integral and discrete transforms, to get familiar with suitable approaches for the solution of concrete problems, to design an algorithm, to implement it and to make the conclusion of this solution. |
