Two questions:
- Is there a reason that my helicorder reading slants/appears wiggly?
- There was a gigantic spike on our weak motion sensor. Thoughts?
Two questions:
Hi Danielle, the accelerometer channels sometimes show this type of fluctuation, it is normal behavior for these types of MEMS sensors. These fluctuations can be easily removed by implementing a highpass filter above about 0.1 Hz.
I’m not sure what the spike is that you showed, but it looks like it’s a “real” piece of data, not an artifact of a sensor-related spike, which are typically lower frequency than that.
