Signal-to-noise ratio (SNR) and co-activation ratio (CAR) for the biceps and triceps sEMG signals as function of activation level. a Signal-to-noise ratios of the biceps (blue) and triceps (red) sEMG signals during the three SVIC and MVIC. b Signal-to-noise ratios of the biceps (blue) and triceps (red) sEMG signals during the three SVIC and MVIC expressed in decibels (dB). c Co-activation ratios of the biceps (blue) and triceps (red) sEMG signals during the three SVIC and MVIC. Note that the error bar is only shown for the MVIC as this measurement was repeated three times
