Does anyone knows any simple way to integrate EMG? Based on the definition, integration is the calculation of area under the rectified EMG signal. Values are summed over the specified time then divided by the total number of values. The unit for integrated EMG is mV*s.
I have no problem in rectified and filtering EMG signal, but I'm not sure whether using the loop concept to process integrate function is a good idea
Thanks

iemg1=sum(abs(x1))/length(x1); % 求积分肌电值
rms1=sqrt(sum(x1.^2)/length(x1));% 求均方根值
