本文对 FIR 线性相位数字滤波器中不同系数的量化影响进行了分析
引入了系数量化偏差函数和系数置化偏差因子的概念
提出了按照系数量化偏差因子进行分步量化的设计方法。该方法设计简单
节省计算时间
性能也比较好
而且适用于高阶数字滤波器的设计。
The quantization effect of individual coefficients on the amplitude response of a digital filter is analyzed and a method of designing digital filters with different quantization steps according to the deviation factor of coefficient quantization is presented.This method is simple
time saving and can achieve satisfactory design performance.It can also be used to design high order digital filters with finite word length coefficients.
