- 在某个音乐厅内，原始音频信号的回音由于墙壁和天花板等的反射而产生，听众所感受到的音频信号是 和它的回音的合成。令y(n)=x(n)+ax(n-k),其中x(n)=cos(0.3pin)+0.5cis(0.6pin),a=0.1,k=50.产生100个样本，使用Matlab工具，求出其自相关，从中观测确定a和k. -In a concert hall, the original audio signal echo the walls and ceilings due to the reflec

- 余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。-Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray
