现代信号处理 一个序列为 ,使用FFT分析其频谱:
1) 使用不同宽度的矩形窗截短该序列为M点长度,取M分别为: a) M=20 b) M=40 c)M=160 ;观察不同长度的窗对谱分析结果的影响;
2)使用汉宁窗、哈明窗重做1)
3)对三种窗的结果进行理论分析及比较。并绘出相应的幅频特性曲线
-Modern signal processing a sequence, using FFT analysis of the spectrum: 1) the width of the rectangular windows with different truncated point of the sequence length of M, take M, respectively: a) M = 20 b) M = 40 c) M = 160 observation windows of different lengths affect the results of spectral analysis 2) Hanning window, Hamming window redo 1) 3) the results of three windows and compare the theoretical analysis. And draw the corresponding amplitude-frequency characteristic curve
