I have an EMG signal and want to calculate mean and median power frequency. There are many different VIs dealing with Power and FFT (FFT Power, FFT, Power, AutoPower,etc.). The LabView Anaylsis FAQ went into a good explaination of these different VIs, though I am still not sure which one to use. I have not run across anyone yet that has to determine mean or median power frequency in LabView. I an using a EMG analysis program that came with our new EMG system. I am trying to replicate the results of there calcuations, but even the power spectrum does not match up. Their customer support has been very disappointing and documentation of calculations are not well documented. I am not even in the ballpark with any of my attempts (other analysis program computes ~85 Hz) Is there anyone who may have any suggestions or sample code for me. It does not seem like a major undertaking and I would have thought that LabView would have already had VIs for these variables as they are popular in kinesiology literature.
Thanks
