硕士课程随机数字信号处理的实验源代码 正弦干扰陷波器-Master degree in a random digital signal processing of the experimental source code sinusoidal interference notch filter

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 f
