I attended the last session of Digital Signal Processing course offered by the Polytechnic of Lausanne (EPFL: École Polytechnique Fédérale de Lausanne) through Coursera.org. The course is presented by Professors Paolo Prandoni and Martin Vetterli. I already knew some of the topics from University, but it was ten years ago and I wanted to refresh my memory and view the same topics from a different perspective.
Note: attending the course was one of the main reasons why I did not post anything recently.
The course has a nice blend of mathematical principles, real-world examples and implementation through MATLAB/Python programming.
The theory is mostly about discrete signals, frequency analysis (the many incarnations of the Fourier transforms are used extensively throughout all the course), sampling, interpolation, and linear filters.
The real-world examples are taken from many different fields of science: the course makes compelling examples on audio processing, image representation…
