The channels shown will be pneumo, electrodermal (Axciton), cardio cuff pressure, movement sensor, and infrared plethesmo (Axciton). In all cases we use a zero phase high pass filter with a fourth order roll off . Unless otherwise noted, all frequency traces are kept with a constant gain to show their relative energy or strength content.enUznanie autorstwa-Użycie niekomercyjne-Bez utworów zależnych 3.0 Polskapolygraph sensor channelsinfrared plethysmopneumoelectrodermalcardioPrawoPsychologiaKryminologiaThe distribution of useful frequencies in polygraph sensor channelsРазделение полезных частот между различными датчиками каналов полиграфаArtykuł2380-055010.1515/ep-2017-0016
