View Full Version : EMG data smoothing

06-20-2007, 11:49 PM
Dear all,

I have collected EMG data from subjects at 1500Hz using a 16 channel Delsys
EMG system though Vicon. Because each trial took 12 minutes, I ended up
with more than a million samples at each channel. I had the analog data
imported to Matlab and smoothed it by using RMS calculation. The
only problem is that it took longer than 10 hours. Is there any alternative
smoothing technique which would work faster in Matlab environment? You
suggestions will be very appreciated.
