白噪 meaning in English
white noise
Examples
- Wavelet packet decomposition based on entropy threshold for white - noise rejection in pd signal
基于门限值小波包变换抑制局部放电白噪干扰 - This method can eliminate the white noise of pd , the tiny pd signal also can be preserved , the distortion is very little and it is suitable the site signal processing . wavelet packet has better decomposition character than wavelet , and can more validly decompose the frequency space of signal
该方法能够很好的剔除白噪，而且把局放信号中较微弱的信号也能保存下来，去噪后的局放波形畸变小，适合现场局放信号的处理。 - A practical approach has been brought forward that the priori information of signal and the external parameter do n ' t needed , on the basis of summarizing the methods of white noise elimination with wavelet and the different lipschtiz exponents and characters in time - scale plane of white noise and pd
本论文在总结各类小波去除局放信号中白噪方法的基础上，根据白噪和局放信号的不同李氏指数以及在时间一尺度平面上的不同特征，提出了一种不需信号的先验知识和外部参数设定的适合局部放电信号处理的实用方法。 - After analyzed the basic principle of optimized noise reduction on tyre pattern , summarized three approaches to noise reduction . the first is trying to reduce size of single block or socket to reduce noise amplitude on time domain , the second is to adjust stripes sorting order and their interlace value to avoid noise - made by every single block - peak values on time domain overlayed and the last is to adjust ratio of blocks and sockets , ratio of stripe interval and stripe sorting order to avoid noise periodical distribution and abnormal high peak values in some frequency strip
论文第四章分析了轮胎花纹优化降噪的基本原理，总结出三条降噪途径：在允许范围内尽量减小单个块或槽的大小、刻刀槽软化花纹块来减小噪声时域波幅度；调整节距排列顺序、花纹条之间的错位值，使各发声单元发出的声压时域波形的同向峰值错开，避免同向峰值叠加；调整花纹块和槽比例、节距比例、节距排列顺序，尽量避免周期性分布，使轮胎所发出的噪声趋于白噪化，避免某些频段的异常高峰值。
