The method of reducing contamination of electrical signals recorded in the presence of repeated interference contamination comprises obtaining an electrical signal recorded in the presence of a contaminating signal, and detecting a timing signal that occurs at a fixed time point during the electrical signal relative to the onset of the contaminating signal. The electrical signal is digitized, wherein the digitizing begins with the timing signal. A plurality of digitized electrical signals is analyzed, wherein the electrical signals are synchronized with respect to the timing signal, to obtain an estimated contaminating signal that is subtracted from the digitized electrical signal. This method can be used with electrophysiological signals, such as EEG, ECG, EMG and galvanic skin response, and for elimination of noise associated with concurrently used methods such as MRI. The method of noise reduction is applicable to recordings of other electrical signals, including audio recordings.

Proposed is a method of multichannel GSR detection for improving measurement accuracy and noise / artifact rejection in measurement of the galvanic skin response on the skin of an individual. The method comprises multichannel GSR signal detection with at least two electrode pairs that are attached to a body of an individual in contact with the skin in different locations, wherein the GSR signals are measured and recorded while the level of excitation of the nervous system of the individual varies.

Time-domain correlation allows not only improved detection of high-amplitude events but also improved sensitivity to smaller events that were ignored in standard bipolar GSR recording.
