说明： 根据滤波器指标选择合适的窗函数，计算窗函数的长度N，调用MATLAB函数fir1设计一个FIR低通滤波器。并编写程序，调用MATLAB快速卷积函数fftfilt实现对xt的滤波。绘图显示滤波器的频响特性曲线、滤波器输出信号的幅频特性图和时域波形图。
(Select the appropriate indicators according to filter window function, calculate the length of window function N, called MATLAB function fir1 design a FIR low-pass filter. And programming, call MATLAB functions fftfilt achieve fast convolution filtering xt. Graphics filter frequency response curve, the filter output signal amplitude and frequency characteristics of maps and time-domain waveform. )

huffmancoding
格式：[huffcodes，氢，領 ，电子] = huffmancoding（磷，氮）
％输入：p是每个字母符号的概率
（如：对= [0.3 0.2 0.2 0.2 .06 .04]）
n是一个整数，决定在每个帧的符号数量
（默认：n = 1时）
％输出：huffcodes：huffmancodes
答：源熵
甲肝：平均熵编码
电子邮件：科丁效率(format : [huffcodes,H,Hav,e]=huffmancoding(p,n)
inputs: p is the probability of each alphabet symbol
( eg:p=[.3 .2 .2 .2 .06 .04] )
n is an integer that determines number of symbols at each frame
(default:n=1)
outputs: huffcodes: huffmancodes
H: source entropy
Hav: average entropy for coding
e: codding efficiency
