Abstract
A linear filter, whose weights are based on the binomial coefficients, is described. It is shown that the phase distortion introduced by the filter is zero and the application of the filter to smoother EP records is illustrated.
摘要
描述了一种线性滤波器，其权重基于二项式系数。结果表明，该滤波器引入的相位失真是零，并说明了该滤波器在平滑心电图记录中的应用。
