Hello Everyone!
I'm working on DSP, TMS320C5402 specifically, and I'm newbie on
this subject...
I need to implement a realtime IIR filter on DSP... can I use DSPLib to
realtime process the samples?
If so, why does the input (x[nx]) variable is an array? Once it uses the
Direct Form 2, it does not need past inputs. The same for output variable
(r[nx])... Can I just set nx to '1'???
Another thing... on documentation SPRU518D, it calls sample-by-sample
filtering = (nx = 1)... does that mean realtime processing? then block-by-block
is when you process the samples stored in a pc file for instance?
If someone has an example of working IIR realtime filtering code, could
please send to me??? :) I'd appreciate a LOT!!!
Thanks for everyone and have a nice day!!!
