IIR
用双线性变换法设计IIR数字滤波器
(1)用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为:在通
带内频率低于0.2π 时,最大衰减小于1dB;在阻带内[0.3π ,π ] 频率区间上,最小衰减大于15dB。
(2)以0.02π 为采样间隔,打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性
曲线。
(3)用所设计的滤波器对实际心电图信号采样序列(在本实验后面给出)进行仿真滤
波处理,并分别打印出滤波前后的心电图信号波形图,观察总结滤波作用与效果。

一系列展示图像压缩技术的源代码。包括有:使用块截断编码的图像压缩(Block Truncation)、基于高斯金字塔变换的图像压缩(Gaussian Pyramids)、基于离散余弦变换对图像压缩(Discrete Cosine Transform)、基于奇异值分解(SVD)的图像压缩(Singular Value Decomposition)。给出的代码还可以用于2D图像噪声消除。(Image Compression
A collection of simple routines for image compression using different techniques.
BTCODE:
Image compression Using Block Truncation Coding.
PYRAMID:
Image compression based on Gaussian Pyramids.
DCTCOMPR:
Image compression based on Discrete Cosine Transform.
IMCOMPR:
Image compression based on Singular Value Decomposition.
The given codes can be also used in 2D noise suppression.
Notes:
The function "conv2fft" performs a 2D FFT-based convolution.
Type "help conv2fft" on Matlab command window for more informations.)
