Physical motivation, definition, properties and application
of Fourier Transform, Discrete FT, Fast FT, 1-dim and higher dimensional FT,
Inverse FT, convolution and deconvolution, theory of distributions
(generalized functions), especially Dirac Delta Distribution
and Singular Value Decomposition are presented
with application in (audio and image) signal processing and in
infra-red spectroscopy.

The student will be able to use Fourier Transform for signal processing and for equation solving, to find the correct sampling frequency and the correct measurement time according to the maximal input frequency and the correct detection of close peaks, to use convolution and deconvolution, to use Singular Value Decomposition.
