MATALAB BASEDSIMULATION IN DEC 2014

本程序是一个数据分类的程序，首先使用KL变换对数据进行降维和去噪，然后用BP神经网络对预处理过后的数据进行分类，并且留有部分的测试集(This program is a data classification program, the first to use KL transform data dimensionality reduction and de-noising, then BP neural network to classify the data after preprocessing, and left part of the test set)

本书系统全面的介绍了现代信号处理的主要理论，具有代表性的方法和一些典型应用(The book is systematic and comprehensive introduction to the modern signal processing theory, representative methods and some typical applications)

pid算法原理解释，对初入学习PID的同学有很大帮助(pid algorithm principle explanation for entering the learning of the students are very helpful PID)

IEC60601-1-8音频报警标准提供了富有和声的音调，以便使它们容易定位、并能防止屏蔽的干扰。范畴与对应旋律的数量都有限，从而能获得容易掌握的不同报警顺序。另外，报警的优先权决定了报警中音符的数量，以及音符顺序的动态特征。这使得人们容易确定报警的紧急程度。这样，IEC60601-1-8标准解决了许多以前报警的限制因素，而且将有助于改善患者的安全性。(IEC60601-1-8 standard audio alarm provides a rich harmonic tone in order to make them easier to locate and prevent interference shielding. Areas and have limited the number corresponding to the melody, so that it can be easy to grasp the order of the different alarm. In addition, the alarm priority determines the number of alarm in the note, and note the order of the dynamic features. This makes it easy to determine the urgency of the alarm. This, IEC60601-1-8 standard solution before the alarm of many constraints, but will also help improve patient safety.)
