Fig. 5From: Motor unit action potential conduction velocity estimated from surface electromyographic signals using image processing techniquesEvaluation of the influence of window lengths on CV estimation in the MLE and IPE methods, for a force level of 20 % of the MVC. The root mean squared error is shown as a function of the length of the window used to estimate the CV, for simulated signals with CV of 4 m/s, at different noise levels: a noise free; and b 16 dB SNRBack to article page
