Abstract :
As is well known, analyzing the frequency components of the EEG is important for the sleeping. There are many methods of studies to analyze the EEG frequency data for recognizing the sleep and its quality, and so on. However, there is no established method for the analysis of the sleeping EEG. For this reason we went for a very useful tool in signal analysis - spectral analysis. An analysis of the variation in magnitude of EEG signals in various frequency bands of sleeping persons was carried out. All the defined bands of the EEG signal of three healthy persons were closely analyzed. The EEG data were collected from internet available for public free download. The aim of the paper is to find out the exact frequency band by analyzing which we can say that whether a person is sleeping or not. Matlab along with “eeglab” toolbox was used for the necessary analysis. It is observed that Delta-Band provides us sufficient information for concluding about sleep.
