有限冲击响应数字滤波器的基础理论。 FIR数字滤波器是一种非递归系统，其冲激响应h(n)是有限长序列,其差分方程表达式为： N为FIR滤波器的阶数。-Finite impulse response digital filter of the basic theory. FIR digital filter is a non-recursive system, its impulse response h (n) is a finite sequence, the differen

FIR(Finite Impulse Response)滤波器：有限长单位冲激响应滤波器，又称为非递归型滤波器，是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位抽样响应是有限长的，因而滤波器是稳定的系统。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。(FIR (Finite Impulse Response) Filter: Finite-length unit Impulse response filter, also k
