自适应相干模板法在心电图机中应用的一种改进算法

An Improved Algorithm of Adaptive Coherent Model In The Application of Electrocardiograph

自适应相干模板法是一种高效的数字滤波器。但原算法在应用时仍存在一定的问题,如在滤除工频干扰和基线漂移时,难以同时兼顾两者的阻带特性。本文对此作了进一步地研究,使该算法同时滤除工频干扰和基线漂移均能得到十分满意的效果。

Though the adaptive coherent model algorithm is a high-powered digital filter, it still has some problems in the applications. For example, its reject responses for removing power-line interference and base-line wander are not satisfied. An improved algorithm is presented in this paper to reach a very-satisfied effect in the removal of power-line interference and baselinewander.
