Re: how should I find noise???

As a rule of thumb, I'd say around 50uV of variance is ok, so this looks good. You're always going to have spikes outside that because of blinking.. but most of it is within 50mV. You say that a dispersion of around 50uV is acceptable, but in the above figure, the vertical axis scale seems to be mo...

Re: how should I find noise???

how should I find noise???

I think there will be a small amount of noise in measuring EEG, but I don't know how to distinguish noise. Can anyone give me some suggestions or a better way to do this?
