Hi, i am working with EEG signal in MATLAB. I have to do wavelet transform (DWT) to EEG signal. My data signal consist of 19 electrode signal. For my signal only C3 and C4 electrode signal contains important information. But i am confused how to work with two electrodes at a time. I can perform DWT to one electrode signal at a time. Is it possible to analyze 2 electrodes at a same time or it is enough to analyze only one electrode???

please help.....

Accepted answer

If you wish to use the DWT, you will have to work with one channel at a time.

You can perform the DWT on each channel separately.

However, you can do wavelet coherence analysis (analyze the joint time-scale properties) of the two time series by using wcoher()

for the reference material and
