Abstract
A Discrete Time Signal Processor for use on the audio path in the Bose QuietComfort® Acoustic Noise Cancelling® [5] Headphones was designed and implemented. The purpose was to demonstrate that digital processing was feasible for this type of portable consumer product, and to design and add new equalization and adaptive abilities not currently available in the all analog circuitry. The algorithm was first prototyped in Simulink® and Real-Time Workshop®¹; it was then adapted to embedded code for an ADI Blackfin® ADSP-BF533 DSP.
