Abstract
In the paper,a 64-channel EEG signal acquisition system is designed using Kintex-7 as the control core and controlled through a three-stage Finite State Machine (FSM) to transmit EEG signals to a computer via Gigabit Ethernet.The simulation and experiment results show that the designed embedded EEG acquisition system can achieve stable and reliable EEG signal acquisition,and the acquired EEG signals meet the requirements.This system provides a solution for portable EEG signal acquisition.
