用0tsu方法和梯度算法分别对图像进行边缘提取

在分析高效宽频带变频系统的基础上提出一种可以把变频部分与多种调制方式灵活结合在一起的方法，并以QAM调制为例，给出具体算法．分析结果表明，该方法降低了对处理速率的要求，提高了处理能力(In order to design an efficient and flexible DDC／DUC system，this paper combined the signal processing of DDC／DUC with QAM system and presented a new method based on the analysis of this efficient broadband DDC／DUC system．QAM modulation was taken for example，and a detailed algorithm of a channel system with 0～30 MHz and 60 channels QAM was presented)

说明：  数学建模在的插值问题的求解，主要用于解决测量问题，如水道测量(Mathematical modeling in solving the problem of interpolation, is mainly used to solve measurement problems, such as water measurement Road)

说明：  信号产生的matlab仿真，包括单位冲激，单位阶跃，符号和抽样信号，内容丰富，适合信号分析同学使用(signal by matlab)
