Hi Hami,

Well the magnitudes of the ECG and EMG signals for the simulated and real examples are completely opposite, so just by swapping the ECG and EEG magnitudes around for the simulated waveform and making the ECG value about x10 the EEG value you will definitely see the R-waves in the EEG+ECG graph.

Trouble is you will get a lot more of the ECG waveform characteristics showing in the combined graph, but at least you will see the R-waves!!

Sorry Hami, but I haven't downloaded the BioMedical Toolkit as yet - I hope to do it some day, but don't hold your breath

Take a look at the attached.  I believe you wanted to filter the ECG out of the EMG, correct?

OK.  Here is EEG filtered out of ECG.  Please compare the two to see what I had to change.  Also, I threw in a filter on the EMG so the "EMG noise" in the ECG would be a little different than the clean EMG data.  This makes the simulation a little more realistic.

i changed EMG with EEG but i can't get good result .

i can't clean EEG from ECG artifact .
