RF noise的用法和樣例：
例句
- It reduces the high-frequency quantization noise generated by imprecisely positioned object edges.
它濾除了由沒(méi)有精確定位的物體邊界信息產(chǎn)生的高頻噪聲。 - The improvement on the edf for the higher frequency noise is better than that for the lower frequency noise in the overlapping estimators and the total estimators.
而相應的重疊估計和總方法估計與之相反，噪聲的頻率越高，其等效自由度越大，這也說(shuō)明重疊估計和相應的總方法估計對高頻噪聲等效自由度的提高優(yōu)于低頻噪聲。
