#5 What is power spectral density?
The unit of PSD is energy per frequency(width) and you can obtain energy within a specific frequency range by integrating PSD within that frequency range.

飽腹感是減肥關鍵!吃這些低能量密度食物,瘦腰又減肥
對於減肥的人來說,最痛苦的事,莫過於每天都要計算食物的卡路里,然後再東挑西揀著吃,又偏偏經常容易肚子餓,於是陷入吃或不吃的天人交戰中。根據一項新的科學研究發現,只要聰明吃低能量密度食物,包括麵食、...
