摘要: The Cornea-Retinal Potential (CRP) is the main source of Electrooculogram (EOG) signals. These potential are in small microvolt and required to be amplified upto applicable usable level. place electrode attachment, eyeball rotation, motion head, ambient light as well conductivity skin can also vary this signal. numerous artifacts with power-line interference other unwanted noise had made EOG signal quite unattractive for any real biomedical applications. This work thus mainly focuses on elimination above major while striving maintain linearity. hardware design part considers cost effectiveness without negotiating accuracy. circuit then rigorously tested checked over varied sample people. It found give an efficient significantly consistent result minimum development a low amplifier acquisition system that counters all problems investigated achieved making it suitable both theoretical research analysis practical
