WebHow to normalize EEG data? Hi, I have some EEG data. There are some that have weaker signal and some have higher signal. May I know how should I normalize each participant EEG signal so that they are at the same range? Can I just use the normalize function where it is using z-score to normalize each signal individually? Please help me, thank you. WebI'd like compare the signals and ultimately hope to derive volume from the chest expansion signal. But first I have to align/synchronise my data. As recording doesn't start at precisely the same time and chest expansion is captured for longer periods I need to find the data that corresponds to my volume data within the chest expansion data set and have a measure …
