We will discus about our new measuring method that can detect EEG under exercising by using an adaptive filter algorithm that we designed. Usually, measuring EEG is done in the quiet state. In case of the measuring EEG under exercising, the gap of the electrode occurs by the vibration of the body by the exercise. It becomes noise and affects the detection of the exact EEG In order to remove a noise, we tried to measure the EEG under exercising used adjustment correlation filter.
