feedback adaptive active noise control

Started by unbe...@yahoo.com January 20, 2010
I am currently working on BF533 EZKIT LITE implementing adaptive feedback system. I am using FXLMS algorithm and the programming style is using double buffering block processing.

May I know if it is possible to implement the application using double buffering programming stlye? Is there any existing product using that programming style to implement active noise control?

Look forward to any reply.
Thank you.

I don't know of any existing products - there may be several. The size of
your buffers determines your time delay and frequency response. Adjust
your sample rate and buffer size to match the algorithm, and then measure
the frequency response. If it works the way you want - great! If not,
play with different parameters to see if you can get it where you want it
to be.

Good luck - should be a fun project!
