Electroencephalography (EEG) is an efficient modality that helps acquire brain signals corresponding to various states from the scalp surface area. The captured brain signals by the EEG machine is called EEG signals. EEG signal is composed of a few characteristic waves with limited frequency-band such as: Wave Delta Theta Alpha Beta Gamma Frequency range (Hz) 0-4 4-8 8-13 13-30 30 and above These characteristic waves are usually used to describe certain human behaviours. In this assignment, you are given a set of EEG signal data measured from a single channel 10-20 system of EEG named T4. 'T' refers to the temporal area, and '4' refers to the position of the right hemisphere brain. The file name is 'T4_EEG.mat'. This file consists of a variable named label as 'ChT4' with details as follows, • total sample N = 2000, • entire time recording is 20 seconds. • frequency sampling fs = 100Hz. To load the signal to MATLAB, use the command 'load ('T4_EEG.mat', 'ChT4')'.
