The electroencephalogram (EEG) is used to diagnose brain injuries and brain tumors noninvasively, as well as in neuropsychology research. EEGs are generally recorded from the scalp, which means the underlying, cortical brain electrical activity must pass through the pia and dura mater membranes, cerebrospinal fluid, skull, and scalp. EEG signal bandwidth is between 0.2 Hz to 100 Hz. The signal is very weak and is easily affected by noise. You have been given a task to design a 4th order filter with Butterworth response in solving this issue. You can use your own value of resistors and capacitor.
