Design of a high-performance EEG acquisition system for unshielded environment
2012
According to characteristics of electroencephalo-graphy (EEG), a high-performance EEG acquisition system for unshielded environment is designed. The whole system is divided into EEG conditioning module, ADC sampling module and data acquisition software. EEG was extracted from human epidermis by EEG conditioning module. ADC sampling module completes the digitization of analog EEG signal. Digital EEG signals transmitted by the hardware are received by the data acquisition software. EEG acquisition experiments are implemented in routine environment. The results of the experiment indicate that the EEG acquisition system can collect EEG effectively and expediently without shielded environment.
