模数 转换器的设计是一个巨大挑战，因为它具有必须在系统级加以考虑的各种不同的输入采样结构。本文将探讨几种通用的输入采样结构，并讨论每种结构对系统其它部 分的影响。-ADC is designed to be a great challenge, because it has to be at the system level to be taken into account a variety of different input sampling structure. This article will explore several common input sampling structure, and discuss each type of structure on the impact of other parts of the system.

本文：采用了FPGA方法来模拟高动态(Global Position System GPS)信号源中的C／A码产生器。C／A码在GPS中实现分址、卫星信号粗捕和精码(P码)引导捕获起着重要的作用，通过硬件描述语言VERILOG在ISE中实现电路生成，采用MODELSIM、SYNPLIFY工具分别进行仿真和综合。-This article: FPGA method used to simulate the high dynamic (Global Position System GPS) signal source of the C/A code generator. C/A code in GPS to achieve sub-sites, the satellite signal capture coarse and fine code (P code) lead capture plays an important role, through hardware description language Verilog in ISE to achieve circuit to generate, using MODELSIM, SYNPLIFY simulation tools were and integrated.

电磁兼容EMC设计的目的就是想办法使自己设计或生产的电子设备产生各种干扰信号的幅度符合别人的要求；同时还要想办法让自己设计或生产的电子设备在受到其它电子设备产生干扰的情况下还能正常工作。因此，EMC标准一般都是强制性的。-Electromagnetic Compatibility EMC design is to seek ways to make their own design or production of a variety of electronic equipment generated interference signal margin requirements in line with the others but also to find ways to help their own design or production of electronic equipment by the other electronic devices interfere with the circumstances can work properly. Therefore, EMC standards are generally mandatory.
