Real-time DSP for adaptive filters: A teaching opportunity

Engineering educators have found that well-chosen demonstrations of digital signal processing (DSP) can result in improved comprehension and better retention of topics for the majority of our students. In this paper, we discuss the 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. A description of the new hardware platform, the demonstration used, and results from a short survey administered to the students regarding the demonstration are provided.
