Dear list members,

Many of us make use of digital filters do remove unwanted frequencies from biological signals. From my experience, students without a strong signal processing background sometimes struggle with grasping the theoretical principles that underlie the design of digital filters.

I recently came across an article that explains some of these principles in a very tutorial and student-friendly way. This article is published on the Sport Sciences website (http://www.sportsci.org/2009/sjejcm.htm). It includes a link to a spreadsheet that allows for a practical application of the principles discussed.

For me, this article has been proven to be a useful teaching tool, and I believe that many of us can benefit from it.
