title: A baseline stabilizer for electrophysiology.
abstract: We describe a circuit that compensates for a slowly drifting baseline without distorting the signal of interest. Implementation of this non-linear filter is quite simple; total cost of components is less than $20.00. The baseline stabilizer should be especially useful for intracellular recording and for recording evoked surface potentials.
