FIR Filter with frequency sampling?

kklobe — Mon, 20 Aug 2007 15:29:13 GMT

Hello,

I'mwondering if it's possible to implement an FIR filter that uses the frequency sampling method with IPP 5.2?

Basically, I want to duplicate the MATLAB FIR2() functionality.

Thanks,

Hi Kirk,

please see expert comments:

No problem if as in Matlab, literally
Let see how fir2 is used
>> f = [0 0.6 0.6 1]; m = [1 1 0 0];
>> b=fir2(30,f,m)
But that is the same as
>> fir1(30,0.6)
If so you can use FIRGen and IIRGen functions in ipps

Vladimir
