Mathematical Methods in Electrical Engineering

Dates for lectures and exercises, see RWTHOnline

 

Small group exercises

There are 22 small group exercises offered. Further information via RWTHOnline.

Note: The small group exercises require registration. (The registration procedure coordinates the registrations for the different small group exercises of the 1st semester in the bachelor program Electrical Engineering, Information Technology and Computer Engineering, so that an overlap-free participation in the registered exercise groups is possible for each student according to the respective prioritization).

 


 

Due to the availability of more and more powerful computers and processor platforms, electrotechnical systems are increasingly realized in the form of “digital” processes. Examples are cell phones, DVB, DVD, CD, MP3, but also professional systems e.g. of medical imaging. This lecture complements the basic modules on analog components and networks with content on digital processes, some of which are implemented on computers under MATLAB. The focus is on mathematical methods for digital processing of audio, image and video signals.

The lecture is accompanied by an introduction to the programming language and development environment MATLAB, which is used to implement the lecture contents on computers.
