英文文本信息熵的计算
说明: 实用C++计算一篇英文文本的信息熵
1、 读取文档,统计英文字母及空格出现的次数;
(将小写字母转为大写字母进行计数)
2、 求概率分布P(X);
3、 根据定义求信息熵。(Computing the information entropy of an English text with C + +
1. Read the document and count the number of English letters and spaces;
(convert lowercase letters to uppercase letters for counting)
2. Calculate the probability distribution P (x);
3. According to the definition of entropy.)

典型序列的产生
一、 实验目的
1. 掌握典型序列的产生方法。
2. 掌握DFT的实现方法,利用DFT对信号进行频域分析。
3. 熟悉连续信号经采样前后频谱的变化,加深对时域采样定理的理解。
4. 分别利用卷积和DFT分析信号及系统的时域和频域特性,验证时域卷积定理。
二、实验环境
1. Windows2000操作系统
2. MATLAB6.0(First, the purpose of the experiment 1. master the method of producing typical sequence. 2. master the realization method of DFT and use DFT to analyze the signal in frequency domain. 3. familiar with the change of the frequency spectrum before and after the continuous signal sampling, deepen the understanding of the time domain sampling theorem. 4. the time domain and frequency domain characteristics of the convolution and DFT analysis signals and systems are used to verify the time domain convolution theorem. Two. Experimental environment 1. Windows2000 operating system 2. MATLAB6.0)
