high frequency noise meaning in English
高频噪声
Examples
- A new fast digital filter of on line eddy current testing system for decreasing the effect of high frequency noise was researched
摘要针对涡流在线检测系统中的各种高频噪声影响，设计了快速去噪滤波算法。 - The large c1 cap rolls off the gain of the regulator starting at a low frequency so that high frequency noise isn ' t amplified by the error amp
这个大的电容c1从一个较低的转折频率开始滚降，所以高频噪音没有被误差放大器放大。 - It is concluded that flp is better than other two filters in reducing the arw , constraining the high frequency noise and reserving the low frequency useful signals
对比的结果表明, flp滤波方法能有效地抑制高频噪声,并保留陀螺信号的有用的低频量。 - The high frequency noises from analog video signal are quantified into digital image . such noises are needed to be weakened or eliminated because they will interfere in eigenvalue identify sequentially in track performance
模拟视频信号包含的高频随机噪声被量化到数字图象中,将影响特征识别进而影响跟踪性能,需要通过数字滤波的方法进行削弱和滤除。 - The detecting accuracy of the beam drift would be improved , as a high performance acoustooptic modulator modulates the frequency of the laser beam drift signal far away from the power frequency , the double power frequency and high frequency noises
具体包括: 1 .利用声光调制器将光束漂移量信号调制到远离工频及其倍频干扰和高频噪声的频带段,以期提高光束漂移量的检测精度。
