利用自适应陷波器来消除通信系统中的工频干扰。重点从LMS算法的步长因子、信号与干扰的频率差、参考输入的幅值和相位等几个方面讨论单频陷波器的滤波效果。另外，还以双频为例，讨论了多频级联型陷波器的特性，证实了经过两次滤波后，信号可被真实的恢复出来，且误差收敛趋于稳定。(The use of adaptive notch filter to eliminate the communication system frequency interference. LMS algorithms focus from step factor, the frequency difference signal and interference, refer to the input amplitude and phase of discussions on several aspects of single-frequency notch filter of the filtering effect. In addition, in order to dual-band, for example, discussed the multi-frequency cascade notch filter characteristics, confirmed the filtered twice, the signal can be restored out of true, and the error convergence stable.)
