N=11，41，81，121时，用矩形窗设计一个低通FIR滤波器，其剪切频率wc＝0.3л(N = 11,41,81,121, the rectangular window design with a low-pass FIR filter, its cut frequencies wc = 0.3л)

给需要的朋友参考 主要是滤波器的设计 大家可以下下来 作为设计的基础参考(Reference to a friend in need is mainly designed to filter down we can make a basis for the design reference)

信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)
