基于双线性变换法的心磁信号降噪初探

利用心磁图来诊断心脏疾病是目前医学界的一种新方法.心磁信号在测量过程中往往会引入各种噪声,这将影响对心磁信号的进一步分析和计算.因此,降低噪声是心磁信号处理中的一个关键环节.利用双线性变换法对心磁信号的降噪处理进行了初步地研究,并结合一些实际的心磁数据进行了比较与分析,从而展现了该方法的实用性.

The Initial study about Noise Reduction of MCG-Signals Based on the Bilinear Transform Method

The diagnose of heart disease utilizing MCG is the new method in medicine. During the measure of the MCG-signals,there are kinds of noise.It affected the effects of the further analysis and calculate.Thus,the reduction of noise is the key in the process of the MCG-signals.In this article,the initial study is shown about the reduction of noise of the MCG-signals utilizing the bilinear transform method,and the practicability of this method is given combining with the actual MCG data.
