designing high pass filter for fpga

[Shivkumar]

Dear Labview users,
                                     I am using compact rio 9002 & FPGA 9101 and labview 8.0.  A signal of 1kHz of sine wave with some DC components will come from a photo detector, here what i have to do is getting only the 1kHz sine wave signal rejecting the dc components. We have newly bought digital filter design tool kit also, but i dont know how to program a high pass filter cut off frequency of 800Hz in the FPGA side with this tool. Can anybody help us by suggesting the way to do this or ship an example of high pass filter cut off frequency of 800Hz for the FPGA side.

Shivkumar,

The user manual for the Digital Filter Design Toolkit provides quite a bit of documentation on filter creation and includes a section on generating a fixed point filter for the FPGA.
Also check out the tutorial Designing Filters Using the NI LabVIEW Digital Filter Design Toolkit.

Shivkumar,

There is also a decent example in the NI Example Finder on Creating a fixed point filter for FPGA that can get you started.

Looking to help,
