a One channel of the “clean” EMG (lateral movement, channel 90); b the same channel of the “pure” ECG interference; c synthetic EMG signal by adding a and b; d the estimated ECG interference; e the estimated EMG signal; f the residual signal between the “clean” EMG and the estimated EMG; g the spectrum of the “clean” EMG (left) and the spectrum of the estimated EMG (right)
