Abstract
In this paper, a toolkit for additional analysis of biophysical characteristics measured by a polygraph is proposed. The galvanic skin response, signals of the upper and lower breathing, photoplethysmogram and tremor are analyzed. The study of biophysical characteristics is conducted with numerical simulation experiments using polygrammes data. Practical evaluation of the proposed toolkit demonstrates its ability to retrieve the additional data and perform an analysis. Areas of a frequency mismatch are identified with the Fourier transformation applied to a photoplethys-mogram spectrum. Principal component analysis is utilized to identify the “stress/no stress” ...
