EEG Data Acquisition System and Analysis of EEG Signals

The main objective of this manuscript is to perform an EEG Data Acquisition, Analysis and Present the EEG signals. It consists of innovative pre-processing method by utilizing amplifier with high impedance and high CMRR. It also consists of Analog filters to remove the noise and to prevent from Aliasing. Analysis is done through FFT algorithm using MATLAB. Findings of the frequency of the signals corresponding to peak magnitude are put forward as the Presentation of EEG signals. As the biomedical signals are having low frequency and low amplitude, the pre-processing, filtering, conversion are done with accuracy, requires adequate sampling rate, processing speed, gain, power consumption and size.
