Claim 6:
7. A system for processing signals during an ablation procedure, comprising: a switching network that comprises: a plurality of switches; a filter comprising: a first filter switch coupled to a filtering control input signal and a primary ablation node that couples to at least one catheter electrode of a catheter; and a second filter switch coupled to the filtering control input signal and a primary ablation connection of a recorder connector; an electrical switching circuit configured to: in response to the filtering control input signal indicating a first state, switch the first filter switch and the second filter switch into the first state which couples the first filter switch to a first connection of an RF prefilter and the second filter switch to a second connection of the RF prefilter; and in response to the filtering control input signal indicating a second state, switch the first filter switch and the second filter switch into the second state which decouples the RF prefilter from the primary ablation node and couples the first filter switch to the second filter switch; and a control circuit configured to switch each of the plurality of switches between the first state and the second state in response to a control signal; wherein each switch of the plurality of switches is configured to: couple the catheter to a recording system; couple, when in the first state, the catheter to one or more devices selected from a group consisting of: a mapping system, an ablation generator, and a stimulator; and decouple, when in the second state, the catheter from the one or more devices.
