The result shows that the ability of anti - interference from strong - narrow band can be improved by using albefaction filter , the interference resisting property of the dual tap filter is much better than that of predicted error filter 仿真结果表明，加白化滤波器确实能提高系统的抗强窄带干扰的能力，同时也表明双向抽头滤波器的抗干扰性能比预测误差横向滤波器的性能要好。
At the same time realizes data collection , data analysis , series of parameters setting , narrow band warning , axis orbit analysis and real time or historical data transport etc . 2 ) precise analysis and diagnosis through lan 并能在监测的同时实现实时信号采集、分析处理、组态设置、窄带报警、轴心轨迹以及实时/历史数据远程传输等功能； 2 、具有网络化精密分析诊断功能。
Applying the ways of adjusting the bandwidth , minimizing the pass band ripples and group delay ripples , a 50ghz filter is designed . in the paper , we also discuss the temperature stability of dwdm thin film narrow band - pass filter 本文总结了波分复用滤光片的各种设计方法,运用带宽调整、通带波纹的减小和通带群延迟波纹减小的方法设计出了50ghz的波分复用滤光片膜系。
In consideration of defects of weak anti - interference ability of strong - narrow band in an orthomode spread spectrum system , it is proposed that an ablefaction auto - adated filter , which is a new method , is used to trace and avoid the interference from the strong - narrow band 摘要针对直扩系统对强窄带干扰的抗干扰能力弱的缺陷，提出了采用白化自适应滤波器来跟踪并消除强窄带干扰的新方法。
Since the spectrum of the helicopter noise contains wide band continuous component and narrow band line component , we can use the wide band signal detection method or narrow band signal detection method . both detection methods are discussed 直升机噪声既含有宽带连续谱成分，又有很强的窄带线谱分量。根据直升机噪声的特点，我们既可以采用宽带能量检测，又可以采用窄带线谱来检测直升机信号。
The fir filter supplies a possible clean signal for further processing . 4 . by processing the sampled signal including contain noise and partial discharge signal , narrow band period signals are filtered , but some period impulse signals ca n ' t effectively be suppressed 4 )通过对局部放电信号的预处理，窄带的周期性干扰信号被滤除，但是一些周期性的脉冲信号由于带宽较宽未能得到有效抑制。
