摘　　要：磁性防窃系统的应用小到钱包,大到机场安检、超级市场以及图书馆等场所。滤波电路是磁性防窃系统信号调理电路的重要组成部分,其设计直接影响到磁性防窃系统的性能与可靠性。本文提出了一种基于可编程模拟阵列(FPAA)的磁性防窃系统方案,对信号调理电路进行了硬件设计与软件仿真,很好地实现了磁性防窃系统的功能。本文针对模拟电路方案与FPAA方案进行了对比研究,得出了这种高性能价格比的FPAA方案对于模拟电路方案压倒性优势的结果。Magnetic anticheft system(MAS) is applied in many places such as wallets,airport security,supermarkets and libraries,etc.Filter circuits are the important parts of the adjustment circuits of a MAS,which directly affects the performance and reliability of the whole system.Not only a MAS scheme based on FPAA were proposed but also the hardware designs and the software simulations of the adjustment circuits which realized the function of the MAS were carried out in this paper.The schemes between the analog circuits and FPAA circuits were researched by comparison in this paper,which affirmed that the high performance price ratio FPAA scheme had an overwhelming predominance over the analog circuits scheme.
