Abstract

This talk discusses digital adaptive filters. We start by exploring what digital filters are, how they work, and what their limitations are. We then extend these ideas to introduce adaptive filters. We survey the main algorithms used to implement these filters, and the different implementations of these algorithms. We weigh the pros and cons of these algorithms, and how they are suited to different applications.

The talk will include interesting Matlab demonstrations of adaptive filters on sound clips in order to remove noise and cancel echo. Lastly, we look into some other applications of digital filters, like human EEG , foetal monitoring, radar signal processing, etc.
