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???

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()
