New Directions in EEG Measurement: an Investigation into the Fidelity of Electrical Potential Sensor Signals

Abstract

Low frequency noise performance is the key indicator in determining the signal to noise ratio of a capacitively coupled sensor when used to acquire electroencephalogram signals. For this reason, a prototype Electric Potential Sensor device based on an auto-zero operational amplifier has been developed and evaluated. The absence of 1/f noise in these devices… (More)
