Delta-Sigma转换器是采用超采样的方法将模拟电压转换成数字量的1位转换器，它由1位ADC、１位DＡC与一个积分器组成，见图1。Delta-Sigma转换器的优点表现在低成本与高分辨率，适合用于现在的低电压半导体工业的生产-Delta-Sigma converters are super-sampling method to convert the analog voltage of a digital converter, which consists of an ADC, 1 Wei DAC with an integrator component, shown in Figure 1. Delta-Sigma converter performance advantages of low-cost and high-resolution, suitable for use in the current production of low-voltage semiconductor industry

设计模式-可复用面向对象软件的基础 设计模式使人们可以更加方便地复用成功的设计和体系结构。将已证实的技术表述成设计模式也会使新系统开发者更加容易理解其设计思路。设计模式帮助你做出有利于系统复用的选择，避免设计损害了系统复用性。通过提供一个显式类和对象作用关系以及它们之间潜在联系的说明规范，设计模式甚至能够提高已有系统的文档管理和系统维护的有效性。简而言之，设计模式可以帮助设计者更快更好地完成系统设计 --引言部分-Design Mode-reusable object-oriented software design based model makes it more convenient for people to reuse successful design and Architecture. Will has confirmed the technical interpreted the model will also design the new system developers more easily understand their design ideas. Design patterns help you make a system conducive to reuse choice and avoid damage to the system design reusability. By providing an explicit classes and objects and their relationship to potential links between the note norms, design patterns can even have increased the document management system and system maintenance effectiveness. In short, design patterns can help designers better, faster completion of system design-- introduction
