Question


Hi everyone , ı use wavedec function for decompase the ECG signal. But location of signal is shifted by wavelet transform. Therefore i cannot find R peaks for original signal. How can ı find locationof R peaks in original signal?
[c,l]=wavedec(nfile,8,'db8'); ca1=appcoef(c,l,'db8',1); ca2=appcoef(c,l,'db8',2); ca3=appcoef(c,l,'db8',3); ca4=appcoef(c,l,...
