Use of the CompactRIO Platform with the LabView Programming Environment for Simultaneous Recording and Processing of Different Types of Bioelectrical Signals

Resumo

A data collection system for simultaneous recording of electroencephalogram and other bioelectrical signals based on the CompactRIO platform (National Instruments, USA), consisting of a chassis with 32-channel NI-9205 modules for recording biological signals, is described. A virtual instrument running EEG signal processing algorithms was developed in the LabVIEW environment for calculation of the amplitudes of the main rhythms, frequency-amplitude, and frequency-time spectra of EEG signals in different leads.
