Hi all, I'm following the EMG manual and I have some questions regarding the filters. How can I reproduce these settings with multi sync?
*Figure 3 below shows an EMG signal with and without filtering. The top signal (blue) is a noisy calibrated EMG signal with no filtering applied. The signal was captured from the calf muscle using Multi-Shimmer Sync software, at a sampling frequency of 1024 Hz. * *The middle signal (orange) is the same signal with a Butterworth band-pass filter applied, with Fc,low set to 20Hz and Fc,high set to 511Hz. It can be observed that the motion artifact has been removed. * *The bottom signal (also blue) is the band-passed signal with a notch filter applied (Fc = 50Hz, bandwidth (BW) = 1Hz). It can be observed that a substantial level of noise has been removed and the EMG signal remains.* I know that there's a filter settings button but I don't know what values should I put in fpass1 fstop1, fpass2 fstop2, passband and stopband. Can anyone help me with this? thank you for your attention, best, David
