摘要
本文利用契比雪夫多项式的特性，提出了一种误差很小的降低几阶多项式阶数的一种可行方法。并给出了在数字滤波器的设计中用此技术获得的可靠结果。
A method capable of reducing the order of nth order polynomials, with small resulting error, is presented in this paper, based on the utilisation of the chebyshev polynomial.Useful sample applications of the order reduction technique on digital filter design are given.
