A sample and hold amplifier system has been described which is capable of eliminating stimulus artifacts from a variety of biological recordings which would otherwise be impossible to interpret during electrical stimulation. Factors contributing to the prolongation of stimulus artifact are discussed in relation to the design requirements of this system. The application of this artifact suppression circuit to monitoring EEG seizures during electrical stimulation is demonstrated.
已描述了一种采样保持放大器系统，该系统能够从各种生物记录中消除刺激伪迹，否则在电刺激期间这些记录将无法解释。结合该系统的设计要求，讨论了导致刺激伪迹延长的因素。展示了这种伪迹抑制电路在电刺激期间监测脑电图癫痫发作中的应用。
