- 研究中我么采用分段的方法对数字音频信号嵌入水印。为便于研 究，以灰度图像为数字水印原始信号经二值化处理后得到水印再嵌入 音频信号的离散变换域中，从而得到嵌入水印的音频信号，其实现过 程原理框图如图1 所示。在水印嵌入的过程主要实现四个阶段的任 务：(1)数据准备与预处理，主要是准备好水印原始图片和待嵌入水印 的音频信号 (2)音频信号分段处理，用于嵌入水印的音频数据部分等 分成(m1*m2)个音频数据段 (3)水印图像降维处理，在此过程灰度图像 水印转化为二值图象,

- 收音机的原理是把从天线接受到的高频信号，经检波还原成音频信号，送到扬声器变成音波把接收到的电台高频信号，用一个变频级电路将它转化为频率固定的中频信号，然后再对这个中频信号进行多级放大，再检波，低放。由于不同频率的无线电波用途较广、接受的-The principle is the radio frequency signal received from the antenna, the reduction by the detector into an audio signal to the
