模态分解去噪 EMD-DFA

【实例简介】在PCB板中实现螺旋走线在任何一个EDA软件中都是比较难实现的。 示例将介绍使用脚本程序直接在AD6的PCB环境下直接绘制出螺旋线，操作简单。脚本有网友编写免费提供分享。

说明：  提出了一种合理的载波相位调制优化方法。该方法结合了子模块的平衡控制，不仅显示了更好的电容电压平衡效果，而且还输出了信号。谐波含量较低。(A reasonable carrier phase modulation optimization method is proposed. This method combines the balance control of the sub-module, which not only shows a better capacitance voltage balance effect, but also outputs a signal. The harmonic content is low.)

安卓权限动态监控系统是一套基于安卓的软件权限和个人应用数据监控系统，实现了敏感权限访问记录生成、网络流量和短信的监控、软件行为分析、用户交互模块采用数据报表可视化的方式，让用户直观地了解到手机中各应用程序访问了哪些敏感权限，是否有非授权流量或短信的流出，同时系统还可视化地给出了应用程序的危险系数和行为分析。(Android permission dynamic monitoring system is a software permission and personal application data monitoring system based on Android. It realizes the generation of sensitive permission access records, the monitoring of network traffic and short messages, the analysis of software behavior, and the visualization of user interaction module by data report forms, so that users can intuitively understand which sensitive permissions are accessed by various applications in mobile phones, and whether there are non-users. Authorized traffic or SMS outflow, while the system can visually give the application risk factor and behavior analysis.)
