Abstract
Evoked potential signal is microvolts (μV) level signal,it is easy to be submerged by environmental noise, noise within the system, and other electrophysiological signals. This paper uses microvolt signal detection technology, multi-lead high-speed data acquisition and constant current electrical stimulation techniques,contains four function module,the electrical stimulator, dual-core controllers, data acquisition circuit and PC,forming a complete set of precision evoked potential system design based on dual-core. The evoked potential system has safety coefficient,strong anti-interference ability and high reliability etc, has a high application value and good market prospect.关键词
