原文:
1. A subharmonic signal is characterized as rational divisions of the fundamental frequency or their integer multiples
2. A chaotic time series is shown as a noisy broadband frequency spectrum.
譯文:
1.次諧波訊號的特性,即可用於合理的區分基頻或其整數乘積值(應該就是基頻值的整數乘積值)
2.混亂時序即顯示雜訊寬頻段的頻譜

次音波訊號特徵就是主要音頻的合理分段,或者是他們的多重整數
一個混亂的時間序列,是以吵雜的寬頻系列來顯示
恕我知識有限,請問這是哪門醫學英文,聽障診斷?
感覺更像analoge或digital 這些現代通訊的東東
