摘要
双T网络带阻滤波器在无线电设备中应用广泛,其对信号的选择作用可以通过传输特性分析给出。用数学法分析双T网络滤波器的传输特性繁琐且不容易理解,由于Multisim 10.0仿真软件搭建仿真电路容易、仪器种类多且使用方便、仿真结果测量和仿真波形观察易于实现,使得双T网络带阻滤波器的传输特性分析简单、便于理解,对该滤波器的使用帮助很大。
The band rejection filter is widely used by the filter through its characteristic curve is analyzed understood. Double T band reject filter ciucut is easily conveniently. Measurement of simulation result is easy. in wireless equipment. Which frequency signal can be rejected The mathematics analysis is inconvenient and is difficult to be constructed based on Muhisim 10.0, its apparatus can be used
