-### Aim of the experiment
+•	To understand and analyze the distribution of frequency in the EEG data at different time bins.
+
+•	To understand the signal processing algorithm-Fast Fourier Transform (FFT).
+
+•	To understand and analyze the average band power (alpha, beta, theta, gamma) of a given frequency band to the overall power of the signal.
