Abstract
A switchable filter device for use in a system for recording electro-physiological signals. The filter device includes a plurality of recording channels, the recording channels having an ablation recording channel. Each recording channel has a patient side terminal at a patient interface and a corresponding recording side terminal at a recording device interface. Each recording channel includes a first signal path with a first frequency dependent transmission characteristic having a first pass band, a second signal path with a second frequency dependent transmission characteristic different from the first frequency dependent transmission characteristic, the second frequency dependent transmission characteristic having a second pass band overlapping the first pass band, and switching devices operable to switch between the first signal path and the second signal path in response to a control signal indicative of a transient interference signal. Preferably, switching from the second signal path to the first signal path is performed with a switching delay after termination of the transient interference signal.
