摘　　要：为研究低压电力线通信技术,有必要对低压电力线通信信道中的噪声进行研究。设计了一种把低压电力线通过耦合网络耦合至示波器的测量方法。耦合网络电路主要包括一个100KHz高通滤波器和一个40MHz低通滤波器。确定了所设计高通滤波器和低通滤波器的相关参数,并进行仿真验证。仿真结果表明:所设计的滤波器可达到较好的滤波效果。In order to study the low-voltage power line communication technology,it is necessary to study the noise in the low-voltage power line communication channel.A measurement method for coupling low-voltage power lines to an oscilloscope through a coupling network is devised.The coupling network circuit mainly includes a 100K Hz high-pass filter and a 40M Hz low-pass filter.The relevant parameters of the designed high-pass filter and low-pass filter are determined.The designed circuit is verified by simulation.The simulation results show that the designed filter can achieve better filtering effect.
