On the compare specifications page it is mentioned that: "Since the noise of the electrode-skin interface also has an pink characteristic, and since the electrode noise at low frequencies is typically well above typical linear Op-amp noise..."
What is the magnitude of 1/f noise of the electrode-skin interface? Is there any way to reduce it by skin preparation?
Our research deals with Delta waves as well, even as low as ~1 Hz. And Theta waves can be as low as 3 microvolts amplitude.
