Webw = blackman (n,'sflag') returns an n -point Blackman window using the window sampling specified by 'sflag', which can be either 'periodic' or 'symmetric' (the default). When 'periodic' is specified, blackman computes a length n+1 window and returns the first n points. Note If you specify a one-point window (set n=1 ), the value 1 is returned. http://www.ijcset.com/docs/IJCSET13-04-08-030.pdf

The Blackman filter has lower side lobes ( - 57 d B ) vs . - 13 d B for a rectangular filter so there will be less ripple in the frequency response of the FIR filter ( in both the passband and the ...

Web窗函数（英語： window function ）在信号处理中是指一种除在给定区间之外取值均为0的实函数。譬如：在给定区间内为常数而在区间外为0的窗函数被形象地称为矩形窗。. 任何函数与窗函数之积仍为窗函数，所以相乘的结果就像透过窗口“看”其他函数一样。 WebApr 9, 2010 · 使用窗函数设计了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 ...
