RF noise的用法和樣例：
例句
- It reduces the high-frequency quantization noise generated by imprecisely positioned object edges.
它濾除了由沒有精確定位的物體邊界信息產生的高頻雜訊。 - 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，雜訊的頻率越高，其等效自由度越大，這也說明重疊估計和相應的總方法估計對高頻雜訊等效自由度的提高優於低頻雜訊。
