Hello,
I would like to know how to do a point by point filter, in the Help the point-by-point filter is referred but it mentions LabView and I do not find how to implemented in C#.
I am using a NarrowbandFirLowpassFilter and NarrowbandFirHighpassFilter. FilterData accepts only arrays
public double[] FilterData( double[] inputData )
If not possible with this filter, can you recommend me which filter to use?

Hi Mohammad,
Thanks for your response.
I see still the method:
public double[] FilterData(double[] inputData)
But I still do not now how to do a point by point filter, calling FilterData seems to delete the history of the Filter, so I cannot call it with over an over with an array with only one element.
So the question remains how to do this: http://zone.ni.com/reference/en-XX/help/375857B-01/mstudioanalysis/point_by_point_analysis/
Bests,

Hello,
The Butterworth filters have history between two FilterData calls.

Hello,
How can I interpret the documentation to know that? I am really struggling with the documentation and examples 😞
And are there also FIR Point-by-Point or only IIR?
Best regards, Ezequiel

It seems that the filters with memory between FilterData calls contains the Reset method.
