| description | The invention provides and realizes a pseudo-wave suppressor for a nerve stimulation and recording system so as to suppress pseudo-waves which are generated in the stimulation process and seriously influence the recording quality. The pseudo-wave suppressor is provided with a three-electrode structure, and the complementary state of reference voltage is achieved through resistors connected between the electrodes and an adjustable sink current generator, so that pseudo-waves generated due to overlarge fluctuation of stimulation voltage can be eliminated at a recording point. The pseudo-wave suppressor mainly has the following two advantages: firstly, pseudo-waves can be suppressed in real time, and the cost is low; and secondly, no blank time exists, and the device is suitable for multi-channel application.
本发明提出并实现了一种用于神经刺激和记录系统的伪波抑制器，以抑制在刺激过程中产生的严重影响记录质量的伪波。本伪波抑制器具有一个三电极结构，通过电极之间连接的电阻以及可调节的灌电流产生器来达到参考电压的互补状态，使得因刺激电压波动过大而产生的伪波可以在记录点得到消除。本伪波抑制器主要具有两个优点：一是可以实时抑制伪波、低成本；二是无空白时间，适合多通道应用。 |
