I'm having trouble finding a definition of "railed" that relates to signal processing.
Am I correct in my guess that this term is in fact from this field?
My signal data comes from an EEG device. The lightly documented open source software I'm using doesn't define it, but it shows that term when there is no signal data being displayed.
Is that all it means (no data)? Or does it mean something like the signal being read is too great to be displayed or correctly measured?
