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) filters: finite impulse response filter units, known as no

运用数字FIR滤波器调理信号，因为FIR滤波器的相频相应是线性的，可以防止时域数据发生畸变，并有效的滤除干扰信号-Conditioned signal using digital FIR filter, the FIR filter as linear phase frequency corresponding possible to prevent the distortion of the time-domain data, and effectively filter interferen
