singal_processing
产生一个连续信号,包含低频,中频,高频分量,对其进行采样,进行频谱分析,分别设计三种高通,低通,带通滤波器对信号进行滤波处理,观察滤波后信号的频谱。(generating a continue time singal,which contains low,middle and high frequences,sampling it.analisize its spetrum.Then designing three kind filters are lowpass,highpass,bandpass filters and processing it.Observing its spetrum.)

fourier_transfer
实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像,中间部分是低频部分,外边是图像的高频部分。经过低通滤波后,图像中的高频成分被滤除掉,只留下低频成分,图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)

Ex11
这个是霍夫曼编码的问题,要求输入只含有ABCD的四句话,且每句8个字符的长度,然后求出四个字符每个的概率,然后当成权值计算霍夫曼编码,我的这个程序已经实现了输入、概率统计、计算出霍夫曼编码存在了bian[]这个数组中(hoffuman decoding)
