  notch filter
Compared with the notch filter and the Least Mean Square (LMS) adaptive filter in previous literatures, the proposed method is more computationally efficient with satisfactory suppression results.
      
Using the method of SA and considering the variance of refractive index as the readout wavelength changes, a practiced notch filter can be designed and the period of the filter is discussed.
      
A novel algorithm of adaptive IIR lattice notch filter and performance analysis
      
A novel adaptive algorithm of IIR lattice notch filter realized by all-pass filter is presented.
      
Two first order and one second order all-pass filters and a notch filter (tunable if current controlled conveyor CCCII is used) are extracted from the proposed configuration.

由于铁道机车信号中噪音信号频率与调频信号频率较为接近,使用普通滤波器很难在滤除噪音时尽可能少地影响有用信号。为此,作者通过引入自适应理论来实现铁道信号中噪音的对消。本文介绍了自适应陷阱滤波器的工作原理,并对其进行了理论推导,设计了用于多频率对消的自适应陷阱滤波器。通过使用该滤波器,成功实现了机年信号中50Hz 奇数倍频率噪音信号的对消。由实验数据可以看出自适应陷波器对特定频率的对消效果突出,对其它信号影响很小,能够满足铁道机车信号分析的要求。
