Abstract :
In their first electronics course, many students find operational amplifiers, analog filters and sensor interface circuitry perplexing and daunting. The purpose of this paper is to present a circuit that addresses these pitfalls. A simplified electroencephelogram (EEG) circuit that is interfaced to a digital backend is proposed. The completed circuit involves using instrumentation amplifiers and filters for the EEG interface. The digital backend helps analyze EEG data on the computer.
