Hi Seeq-

As shown in the following screenshot, I have a signal that occasionally spikes.  I'd like to remove these spikes (both the high and low spikes) before I do any additional analysis using this signal.  I tried to do this with the Low Pass Filter, but I didn't get the required results.

Hi Curious George,

This is best accomplished using the .removeOutliers() function in Formula.  

Navigate to Formula from the Tools menu:

Apply the .removeOutliers() function to your input signal:

The new signal, shown in green in the second lane, no longer contains these large spikes.

Please let me know if you have any additional questions.
