AM信号的循环谱的matlab代码实现，初学者适合 (The AM signal of the cyclic spectrum of matlab code, suitable for beginners )

当前工程上广泛采用了一种高效滤波器，即CIC（cascaded integrator-comb filter）将其作为第一级来实现抽取、低通滤波。第二级再用一个普通的FIR滤波器就实现使后端设备工作在较低的频率下且硬件花销少、功耗也很低。(Widely used in the current project, a highly efficient filter, that is, CIC (cascaded integrator-comb filter) as the first level to achieve the extraction, low-pass filter. An ordinary second-class and then the realization of the FIR filter so that the work of the back-end equipment at a lower frequency and spending less hardware, power consumption is very low.)

U盘控制芯片CH331,CH331 是一个小容量U 盘的控制芯片，只要外加一个串行存储器芯片，就可以实现2KB 到512KB 的小容量U 盘。(U disk controller IC CH331, CH331 is a small-capacity USB control chip, As long as plus a serial memory chips, we would achieve 2 KB to 512 KB of small U disk capacity.)

a.阅读的图像img_1.tif，img_2.png的文件夹中，并 他们展示于一体，这两个数字分别。 （参考函数：imread, imshow, figure, subplot） b.在matlab，观察从工作区中的图像信息面板 c.分别使用size, imfinfo,whos等功能获得的图像信息 d.添加标题的图像。 （参考函数：title） Ë 。下面的代码实现的M文件编辑器 f=imread(‘img_1.tif’) imshow(f) set(figure(1), NumberTitle , off , Name , my first image’) 观察结果，并确定的功set() f。保存img_1.tif目录“D： imagetest”。如果该文件夹不 存在，请首先创建这个新的文件夹。 （参考函数：imwrite） (a. Read the images img_1.tif, img_2.png given in the folder, and show them in one and two figures respectively. (referenced function: imread, imshow, figure, subplot) b. In matlab, observe the images information from the workspace Panel c. Use size, imfinfo,whos,etc functions to obtain image information respectively. d. Add title to the images. (referenced function: title) e. Implement the following codes in the M-file Editor f=imread(‘img_1.tif’) imshow(f) set(figure(1), NumberTitle , off , Name , my first image’) observe the result, and determine the function of set() f. Save img_1.tif to the directory “d:imagetest”. If the folder does not exist, please create this new folder first. (referenced function: imwrite))

说明：  ofdmIM仿真系统设计源代码，有不对的地方请指教谢谢大家(Ofdmim simulation system design source code, there are wrong places please advise, thank you)

说明：  在二维 RGB 图像中嵌入水印，其中图像的大小和水印图像的大小可以不一致(2D RGB images embedded watermark, which images the size and the size of the watermark image can be inconsistent)
