WebMay 10, 2011 · Hi, I'm having an issue in Labview (I'm using 8.2) with being able to apply a filter to some data, so I have recorded a 2D array of double (64-bit digit) where one column represents a time in ms, and the second a standard deviation of position, I wish to apply a highpass filter to this so that motions with a frequency of >10Hz are removed from the … WebJust as a recap: Lowpass filter passes anything below the set freq. Highpass filter passes anything above the set freq. Bandpass filter passes anything between the set freq. Bandstop filter passes everything except the part between the set freq. The Butterworth part has nothing to do with high, low or bandpass but with how fast the fall-off is ...
