Sorry but it may seem like an obvious question because I am new to EMG analysis but I have been reading many papers on how various research groups clean, filter, segment, and classify muscle activation and fatigue using time, frequency, and time-frequency domain analyses. However, I am struggling to find a common protocol for taking a raw EMG signal, processing it such that I can feed it into to these different types of analyses. Is there a general repository or guideline or protocol or flow chart that is generally accepted that someone can point me to? Any help would be much appreciated.
