摘要
在分析了正交信号检测原理的基础上,将正交检测技术应用于周界入侵探测装置中,搭建了正交信号检测电路,应用Multisim8软件进行了仿真和分析。
Based on analyzing the quadrature signal detection principle, the quadrature detection technology was applied to perimeter intruder detection system. The circuit of quadrature signal detection was established. Simulation and analysis of circuit were accomplished by Muhisim8 software.
