EEG Signal Processing To Detect The Human State Using LabVIEW

The paper presents the detection of the state the human being is in by analyzing the EEG signals of the brain. Different states of human being are waking state,dreaming state and deep sleep state.as these states change the frequency of the brain waves which are represented by EEG signal changes. The EEG is generally divided into four different types of waveforms with respect to their frequencies Delta (0 to5-3) Hz, Theta (4 to-7)Hz, Alpha(8 to-13)Hz and Beta(14 to 30)Hz. These four waveforms are basic waveforms of EEG.The EEG signals are recorded by placing electrodes on brain and can extract by using the LABVIEW.with the help of DAQ board the EEG signals can be analysed by using LABVIEW software.
