I have a EMG signal of 30000x4. with sampling frequency of 10KHz.
I filter noise by below code
NotchFilter = bandstop(Data01Raw,[49.9 50.1],Fs);
sEmgFilter = bandpass(NotchFilter(:,1:2),[20 500],Fs);
iEmgFilter = bandpass(NotchFilter(:,3:4),[600 2000],Fs);
Data02Filtered = [sEmgFilter iEmgFilter];
in above code bandpass or bandstop occur by which filer like is it butterwork or cheby or ellip?
I need to fiter the signal using butterworth 2nd order. How can i do this?
