勒让德多项式 legendre polynomial expansion
- 勒让德多项式和函数;
Legendre polynomials and functions; - 分析了几种经典的滤波器原型设计原理及其自身不足,基于勒让德多项式,给出了一种新的低通滤波器设计原型。
Based on Legendre multinomial, a new kind of low-pass filter prototype is designed out after analyzing the design rule and inefficiency of some classical filter prototypes. - 一般多项式都可以展开为正交多项式的级数形式,而勒让德多项式、厄米特多项式和拉盖尔多项式都是典型的正交多项式。
All ordinary polynomials have series expansion of orthogonal polynomials, while Legendre polynomials, Hermite polynomials and Laguerre polynomials are special orthogonal polynomials.
