Definition: A baseline drift refers to a gradual change or deviation in a signal’s behavior or output over time. Changes in the contact between the sensors and the scalp, temperature variations, instrument instability, and other variables can all contribute to this change.Definition: A baseline drift refers to a gradual change or deviation in a signal’s behavior or output over time.
