“…The role of the low-pass filter is to filter out environmental high-frequency noise interference, mainly environmental radio waves, power supply ripple, and noise caused by active devices themselves [53,54] . Common low-pass filters used for the analog front-end of EEG acquisition include the RC filter, switched capacitor filter and Gm-C filter.…”

Epilepsy is a common neurological disorder that occurs at all ages. Epilepsy not only brings physical pain to patients, but also brings a huge burden to the lives of patients and their families. At present, epilepsy detection is still achieved through the observation of electroencephalography (EEG) by medical staff. However, this process takes a long time and consumes energy, which will create a huge workload to medical staff. Therefore, it is particularly important to realize the automatic detection of epilepsy. This paper introduces, in detail, the overall framework of EEG-based automatic epilepsy identification and the typical methods involved in each step. Aiming at the core modules, that is, signal acquisition analog front end (AFE), feature extraction and classifier selection, method summary and theoretical explanation are carried out. Finally, the future research directions in the field of automatic detection of epilepsy are prospected.

“…Henceforth three standards op-amp are used in construction of an instrumentation amplifier where the outputs of op-amps 1 and 2 are fed to op-amp3 as input, the amplified final output will be taken from the op-amp3. The second order low pass filter removes the higher frequencies that are above the frequency range of EoG signal [8] as in Fig. 5, the input and output signal voltage will be equal by making gain =1 considering the C1=100nF, C2= 100nF, R1= 22kΩ, R2=120kΩ as in Fg.5…”

To examine the biomedical signals from the human body is of a challenging task. Signal acquisition of the biosignal needs proper design methodology with the estimation of consequences further. In this paper we discuss about the signal acquisition of EoG using the surface electrodes and to amplify the weak biopotential signal an amplifier is proposed with the additive noise reduction filter. The biopotential instrumentation amplifier is designed using standard operational amplifier that posses the high voltage swing. However the major artifacts present in the EoG signal acquisition is because of power line interference can be eliminated by notch filter.
