Hi, I just want to the exact step in pre-processing EEG signal.
Step 1: convert time-based data into frequency-based data
Step 2: filter the signal to make sure only the wanted frequency is available (eg: 0.5 Hz - 50 HZ)
Step 3: remove any artifacts
Step 4: Divide the clean signal into 4 bands (alpha, beta, theta, delta)
Is these steps correct?
