DSP
说明: 数字信号处理设计与仿真分析
(1)建立两个模拟信号的数学模型 sa1(t)和 sa2(t), 其中 sa1(t)是有用信号, sa2(t)是干
扰信号。 两个信号的中心频率、信号带宽等参数由学生自己选定,要求两个信号的频谱不重
叠, sa2(t)的幅度比 sa1(t)的幅度高 20dB, 两个信号时域叠加得到合成信号 xa(t), 即
xa(t)= sa1(t)+ sa2(t)
设计计算机程序仿真产生 sa1(t)、 sa2(t)、 xa(t)信号, 分别画出三个模拟信号的时域波
形和频谱图;(Establish two mathematical models of analog signals sa1(t) and SA2 (t), where SA1 (t) is the useful signal and SA2 (t) is the dry signal
Interference signals.)

Insert-matlab-intotext
在文本文件中嵌入MATLAB代码并运行返回结果
类似在HTML中嵌入PHP和ASP代码,本函数实现在文本文件中嵌入matlab代码并运行!
主要作用以及价值:
在文本文件中嵌入matlab代码,并可以直接运行该文本文件
根据matlab变量的当前值,实时修改文件文件中相应的数据
目前具有如下功能:
matlab代码使用必须包含在< >符号中,中间的内容都被解析为matlab代码
matlab代码可以放在文本的任意位置,你想放在什么地方都可以
matlab代码允许被文本分割而不连续书写,比如循环语句
fprintf(fid_target,...)函数用来向文件中写入字符,目前还比较麻烦
有待改进的方面有:
在文本文件中增加对matlab function的支持
简化变量输出,目前只能fprintf(fid_target,...)
目前是M脚本完成功能的,后期会提供M函数(MATLAB code embedded in the text file and run return results
Similar PHP and ASP code embedded in HTML, the function matlab code embedded in the text file and run!
A major role as well as the value of:
Matlab code embedded in the text file, and can be run directly on the text file
Modify the data file file based on the current value of the matlab variables, real-time
Currently has the following functions:
matlab code uses the symbol in the middle of the parse matlab code must contain
matlab code can be placed anywhere in the text, where you want to put
matlab code allows text segmentation without the consecutive writing, such as loop statement
fprintf (fid_target, ...) function is used to write characters to the file, there is too much trouble
Areas for improvement:
Increase support for matlab function in a text file
Simplify variable output, can only the fprintf (fid_target ...)
M script completed, late M function)
