摘要:本文主要基于对切比雪夫多项式概念的回顾、定义以及其定理的推导,得出连续函数的逼近多项式,根据其性质分析研讨了切比雪夫多项式在matlab中的应用。对于现在被大量研究的滤波器问题,研究讨论比较切比雪夫滤波器和普通滤波器的异同。在处理中问题时最常遇到的基础的操作滤波器,并且在最通用的选择滤波器设计中使用多项式逼近,根据零点插值的相应数据,在 matlab中均可以得以实现。29227 毕业论文关键词:切比雪夫多项式;数字滤波器 ;matlab
Chebyshev polynomial and zero point interpolation of matlab
Abstract: In this paper, It is based on a review of the concept of chebyshev polynomial, definition and theorem of deduction, it is concluded that the continuous function approximation polynomials, according to the nature of the analysis on the chebyshev polynomial in the application of matlab. For filter problem is now a large number of research, research discussed cut than snow, filter and general filter, as well as the similarities and differences of the base of our problems are most often encountered in processing the operation of the filter, and the choice of the most common use of polynomial approximation in the design of filter, and by the corresponding data of zero point interpolation, we all can be realized in matlab.
