| Biomedical signals are usually low amplitude and high bandwidth signals. EEG signals are very low amplitude (generally less than 300 μV) and very high bandwidth (range from 0.5 to 100 Hz), too. EEG was used to assist in the diagnosis of brain damage, Alzheimer disease and Parkinson disease, and certain mental disorders. In this study amplifier and filters designed with CCII+ and these simulations are performed with PSPICE program. Normal brain signal, the Alzheimer brain signal, epilepsy brain signal are compared, the shrinking hippocampus compared 25 years old normal brain, 75 years old normal brain and 75 years old with the Alzheimer brain. |
