Multi-channel amplifier system for computerized topographic EEG analysis.
Topographic analysis of EEG and evoked potentials requires the computer processing of data from multi-lead recording. The use of 20 or more channels is now quite common, straining the resources of the usual EEG machine. We present a design for a high gain, low noise, 32-channel amplifier matched to computer data acquisition requirements. Low cost and small size are additional benefits to the design.
