Linear Restoration of Cellular Action Potential

Zhu Yisheng Gu Hong Lian Chenna(Department of Biomedical Engineering, Shanghai Jiaotong University)  
Based on the theory of square wave restoration, a novel method to remove the noise of Action Potential (AP) is presented. The whole processing procedure consists of three steps, i.e., inputting the noisy AP signal to a lowpass filter, constructing a corresponding square wave according to the output of the lowpass filter and then applying it to the wave forming filter to get noise free AP signal. It is demonstrated that the method can remove the white noise added to the optical AP signal effectively, thus noninvasive detection is achieved.
