周期性干扰 meaning in Chinese
periodic interference
Examples
- The repetitive control ( rc ) theory is a new theory based on internal model ( im ) principle
重复控制是基于内模原理的新型控制理论,是抑制周期性干扰信号的有效方法。 - 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。 - Because period narrow band signals are the main part of background noises , this thesis uses hardware description language to design a multi - band finite impulse response filter ( fir ) and downloads the program into filed programmable gate array to eliminate the period narrow - band interferences in the background noises
3 )在现场环境中,背景干扰主要是周期性的窄带,本文利用硬件描述语言( vhdl )设计了一个多带fir有限冲击响应滤波器。应用到可编程逻辑器件中,消除了背景噪声中的周期性干扰,为信号的进一步处理提供尽可能干净的信号。 - In this paper , eliminating the periodic narrowband noise with wavelet packet has been put forward . the periodic narrowband noise eliminating method has been proposed that has the optimal wavelet packet base . the instances show that this approach can eliminate the periodic noise of pd signal , and its dose not need set the external parameters
通过分析周期性干扰和局部放电信号的小波包分解特性,采用了最优小波包基来剔除周期性干扰,实例证明能够很好的剔除局部放电信号中的周期性干扰,并且不需要外部参数设定。 - On the basis of the theory and the experiment , the paper has synthetically analyzed the anti - interference characteristics of the hardware method ( differential balance ) and software method ( digital filter ) . the paper has presented that these two methods have some disadvantages respectively . based on this fact , a new method has been presented . hardware method can be use to restrain periodical interference , and software method can be use to discriminate pulse polarity
从理论和试验两方面,综合分析了硬件措施(差动平衡法)和软件措施(数字滤波法)抑制干扰(包括周期性和脉冲性干扰)的方法和特点,指出了两种方法各自存在的缺点,在此基础上提出了用硬件方法抗周期性干扰,用软件抗脉冲性干扰的新方法,并通过试验证明,该方法可以抑制周期性干扰,有效地鉴别出外部干扰信号和内部局部放电信号。
