CrossCorrelationFilter

Bases: SignalFilter

Preprocesses EGMs by removing harmonics (40Hz), baseline, and QRS- complex. Additionally, applies derivative, botteron filters, and normalize EGMs. If ECGs are added to the EGM signals, then a farfield filter will be applied using these ECGs and default ECG annotator properties.
