摘要
本文介绍用于电生理信号测量的可编程滤波器设计方法。采用最小二乘拟合算法,通过计算机实现滤波器的自动校准。实践证明,该滤波器能提高测量系统的适应性,且提高了系统测量精度。
The method of designing the programmable filter used in signal measurement of electrophysiology is described. And the Least Square Fit is applied to calibrate a series of parameters automatically. The experimental result shows the adaptability and precision of the measure system with the filter are improved remarkably.
