Hello,
I’ve tried three types of electrodes: Cognonics dry flex sensors, Foc.us dry electrodes, and a pair of electrodes. I’ve been using only two electrodes from each type. The electrodes output go into a differential analog input of an ADS1298 which I’m connecting to a Raspberrypi for signal processing.
I’m only using the differential input (only two electrodes) But I’m also using a filter in my signal processing code that is supposed to cancel out the 50 Hz component. Isn’t that enough ?
Thanks again,
Best regards,
Insaf.
