Course objectives
The course is aimed at providing several advanced methods of spectral analysis. The first part of the course is focused on different transforms including Z-transform, discreet Fourier transform, Laplace transform, and Radon transform and their applications in solving difference and differential equations. The second part is devoted to multiresolution analysis and wavelet which have applications in signal processing.
Learning outcomes
At the end of the course students should be able to: - understand and explain discrete analogs to the relevant concepts and operations from Spectral Analysis I - describe the fundamental properties and use of Z-transform, Fourier transform (discreet Fourier transform), Laplace transform and Radon transform. - Master the main techniques and use of multiresolution analysis and wavelets.
