hello friends,

i am using blackfin adsp bf537 for embedded and signal processing purpose.
application is multiple gas analyzer and making first prototype of it.i want to smooth digital
signal and to remove noise. so after analog to digital converter, i will use bf537. but, i am
still puzzling for signal processing stuff. should i have to use kalman filtering or moving
average filtering for smoothing and noise removal purpose of real time signal? or can i do this
stuff using bf537? please give me your suggestions. if you want further data on it , let me
know.

regards,
Jal

The bf537 should have no problem filtering your data.  You should try many
filters, and one way to do that is to play with some sampling of real data
on a PC.  If you take several blocks of data, each with a few thousand
samples, you can compare the output from different filters.  Check out
http://www.dspguru.com/ for some ideas on what filters to try and where to
find filter making tools.
