利用 MATLAB 实现窗函数法设计 FIR 滤波器，主要是选择合适的窗函 数进行截断运算 (Window function method using MATLAB to design FIR filter, main is to choose the appropriate letter for window blocking operations.First theoretically to approximate the unit impulse response of ideal filter hd [k], to be determined by the passband and stopband attenuation index window function types, determined by transition zone FIR filter order M length (or N), and finally USES MATLAB to calculate the window function value, and hd wN [k] [k] value, so that the design of FIR filter h (k) MATLAB provides the blackman window function is: w = blackman (N) Where N is the length of the window function.)
