An inexpensive approach for teaching adaptive filters using real-time DSP on a new hardware platform

Carefully chosen demonstrations and hands-on exercises of digital signal processing (DSP) concepts can result in improved comprehension and better retention of topics for the majority of our students. This is especially true when the instructor has limited time to present a specific topic. In this paper, we describe the in-class use of a demonstration using real-time DSP to implement a basic adaptive filter for noise cancellation, utilizing newly-available DSP hardware from Texas Instruments. We provide a description of the new hardware platform, how the demonstration was used, and the results from a short survey administered to the students regarding the demonstration.
