Abstract
An electrophysiology system including signal channels each of which processes an electrophysiological signal along a signal path extending from an input port that receives the analog electrophysiological signal, via an adjustable gain element that amplifies the electrophysiological signal, and via an ADC element that converts the analog signal into a corresponding digital signal, to an output port. The system further includes a monitoring element that generates a monitoring signal representative of a DC component of the electrophysiological signal and a gain control element that generates a control signal responsive to the monitoring signal. The control signal controls the gain setting of the gain element to cause a decrease in gain, if an increase in the magnitude of the DC component is determined; and/or an increase in gain, if a decrease in the magnitude of the DC component is determined.
