Part Number: ADS1299EEGFE-PDK Hi, I am trying acquire the EEG signals from a real patient using ADS1299 EEGFE-PDK. I have placed 1 electrode on the forehead and another on the earlobe as reference. I am not able to detect the EEG signal but rather a periodic signal of 50Hz. I know this is due to powerline interference, I have tried performing the same analysis using a laptop and EVM powered by battery abd still the problem remains. Is there a solution for this? also apart from 8 channel electrodes ADS1299 has bias and reference electrode, but for measuring EEG signal we need reference and ground electrode. Where do i connect the ground electrode? I have tried measuring a standard signal from function generator and the results seem to be correct, only when I measure EEG signal from a human being the results are not correct. I have attached the images for the test i performed.
