摘要
介绍了用于测量电源线中的宽带电磁干扰（ＥＭＩ）的Ｒ型、Ｃ型和Ｔ型等３种无源ＲＣ陷波电路（ＮＣ），并对它们的电压传递函数、陷波频率及负载的影响等进行了理论推导和分析．这些ＮＣ具有深陷波、宽通频带和易于实现等特点，可适用于不同要求的测量场合及其它电子设备中高要求的单频ＥＭＩ抑制．
Three kinds of passive RC notch circuits(NC):R,Cand T for wide-band measure-ment of EMl on the power line are intruduced.Their characters for voItage transmissionfunction,notch frequency and effect of load are derived.These NC have some feature such asdeep notch,wide pass-band and easily implementation. They can be used in different situa-tions.
