Hi, I am working with a displacement transducer, which I get voltage adquisition and a noisy signal.
I was trying to filtering signal using "Median Filter" but without success. Maybe I have a mistake using "right rank" and "left rank".
So I hope you can help me and get a better signal.
Attached the images and VI.
Solved! Go to Solution.
I suspect the filter is working as expected, but since you're outputting to a waveform chart, it's stacking the entire DAQ waveform output end-to-end, one after another and you're getting strange 'looking' results because of that.
Try a waveform graph instead.
Thanks for answer.
Ok I will try again with a waveform graph. So I have another question now, I need to calculate the derivative for certain range of signal, because I need to get the velocity from the displacement sensor. Do you think there will be no problem using waveform graph instead waveform chart?
Regards Mr. mud_light.
I wouldn't expect there to be any difficulty calculating a derivative. The waveform graph is just a device through which the data may be visualized, the actual calculation will be performed using the data you've collected. :-)
