本文提出了一种基于独立分量分析的音频数字水印方法。嵌入水印时,对原始音频文件进行一级小波分解,在分解 得到的逼近分量中利用随机混合方法嵌入水印后进行小波逆变换形成嵌入水印的音频文件。仿真实验结果表明这种方 法的强鲁棒性和可行性。(Abstract:Audio p roduction is one of the important digital multimedias, which transmit becomes more and more convenient. To p revent the multimedia content from being stolen or illegally used, audio content p rotection techniques become increasingly impor2 tant so that the potential of these app lications can be reached. As the importantmethod of copyright p rotection, the digitalwater2 marking technology has been acquired widely recognition and research. This paper p resents a method of digital audio watermark2 ing based on independent component analysis. When embedding watermarking, the original audio is decomposed by single2level discrete 12D wavelet transform, watermarking is embedded by mixing randomly to the app roximation coefficient vector obtained, and the audio is single2level reconstructed receiving audio havingwatermarking. Emulated experiment results show that thismeth2 od is robust and feasible.)

这个程序用于求解任何一年的任何一个月有多少天。可以直接使用(This program is used to solve the number of days in any month of any year. Can be used directly)

【实例简介】STM32F407_ADC_DMA_FFT 使用STM32F407内置ADC，可控制采样频率为512KHZ、256KHZ、128KHZ，采用定时器 DMA ADC的方式不断读取输入电压，进行FFT，之后再将结果通过串口的方式打印出来，可以修改采样频率与点数，体验一下FFT的神奇之处。

STM32单片机通过PA IO口采集ADC信号并通过串口传输到上位机。
