REAL TIME REGISTRATION OF THE ELECTROPHYSIOLOGICAL SIGNALS SPECTRA

The paper deals with the issues of spectra acquisition for the electrophysiological signals, diagnostics result dependence on the noise level and expert’s qualification. A real-time module for amplitude-frequency spectra estimation of electrophysiological signals is designed. A general diagram of connection between measuring module and spectrum analyzer (as a part of multifunctional diagnostic system) is shown. The module is realized on the base of Cubieboard A20 minicomputer. It provides continuous decomposition of signals (up to 32 channels) into fragments of equal length and their independent mathematical processing for each measuring channel. The suggested device makes it possible to analyze the real-time dynamics of spectrum changes.
