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

射频低通滤波器设计，用ADS和matlaB两个程序仿真作对比，75.7MHz，在100.7MHZ处衰减20db-Redo the example, but the cutoff frequency and stopband frequency change to 75+0.7=75.7MHz and 100+0.7=100.7MHz, respectively, and calculate its frequency responding curve by using ABCD matrix.

backpropagation algorithm for train nn but it have some problem. its need to redo
