Figure 2From: Assessment of validity of a high-yield surface electromyogram decompositionNoisy firings and comparison of action potential shapes. A: Firing spikes of exemplar MUs. The vertical bars represent the originally decomposed firing events, and the circles represent the firing times with added Gaussian noise (SD = 0.1 * SD of ISIs). B: A comparison of action potential estimates from 4 channels of EMG signals.Back to article page
