心电信号在进行后期分析时希望尽可能不损失QRS波的形态 ,文章据此设计了两种类型的滤波器 :基于Chebyshev一致逼近理论的等纹波FIR滤波器和基于零相位实现形式的IIR滤波器 ,并给出了其频率特性 ,实现方式和处理结果。
ECG signal in the late analysis hope that as possible without loss of QRS wave morphology, the article accordingly designed two types of filters: based on Chebyshev uniform approximation theory of the ripple FIR filter and phase-based implementation of the zero-phase IIR Filter, and gives its frequency characteristics, implementation and processing results.
