Hello guys ,
how can I can I realize a smoothing filter in fpga as my signal is dc and its with noise Since I need the filtering and averaging to be done very quick .
Solved! Go to Solution.

Can you quantify 'very quick'?
Rather than try filtering, is it feasible to remove the noise from source? A filter will introduce delays
If noise is picked up along the signal path, you could amplify the source and increase the signal to noise ratio.
Given a quantified sample rate, would your FPGA be able to oversample and average?
Have you looked at the vi.lib filtering VIs?

hi yenknip,
i cant use an amplifier near the source since its a very just environment , amplifier will surely fail. and i want the manipulation in fpga to be done in more than 10 mhz since the whole process is being done within millisecond . i use c series 9205 data to acquire the data.
