Zusammenfassung:	Systems and methods are described herein for estimating and filtering electrophysiological signals. In some examples, a noise filtering system can be employed to receive at least one electrophysiological signal. A signal segment extractor of the system can extract a signal segment of interest from the electrophysiological signal. The system employs a signal segment noise calculator to evaluate the extracted signal segment of interest to estimate a noise in the signal segment of interest. The estimated noise can be provided to a signal segment filter of the system to determine a surrogate noise estimate for at least one remaining signal segment of the electrophysiological signal for noise filtering the at least one remaining signal segment. The signal segment noise calculator can be configured to filter the signal segment of interest based on the estimated noise and the filtered signal segments can be combined to provide a filtered electrophysiological signal.
