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. )

image-construction-by-fft-and-wt
傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR
