Ying Sun · Keisou gijutsu · 2008
An amplifier AD604 is introduced in this paper,which has ultra low noise and variable gain according to exponent orderliness.It is used to shape evoked potentials stimulus.Also a high performance,low-cost multifunctional PCI card including its application in medical instruments are presented.Then the evoked potentials measuring apparatus based on this card are discussed.The acquisition of weak signal of brainstem-evoked potentials is achieved.
