Hello everbody,
 
I need some help for using the filter2 opcode.
 
I can get the Bh and Ah vectors as the filter coefficents with corresponding number of poles and zeros from Matlab.
 
But after  implementing the filter with the filter2 opcode, the result has been zero output.
 
Could someone please send us an example?
 
Thanks for your help,
