Narrow band electroencephalographic amplifier |
| abstract |
A low-noise, high gain differential amplifier suitable for EEG amplification is constructed in a shielded metal enclosure. preferably on a ground plane circuit board. The amplifier is battery powered to eliminate all possibility of noise from the power system. The amplifier utilizes a pair of operational amplifiers to provide high input impedence for each of two input signals. A differential amplifier generates an internal signal which is filtered and amplified by a pair of band-pass amplifiers and overlapping low-pass and high-pass amplifiers. |
