I recently started measuring EMG, EKG, and EEG signals with the Ganglion Board, but the problem is that I’m not getting a clean signal—it’s full of noise. Even though I measured the impedance, and it’s in the green range, I’m still having issues. Can someone please help me? It seems pretty easy, but it’s just not working. Here’s a photo of the EMG signal; no matter what I do, I only get this.
