Webb5 jan. 2024 · Power Spectral Density. The distribution of average power of a signal x ( t) in the frequency domain is called the power spectral density (PSD) or power density (PD) or power density spectrum. The PSD function is denoted by S ( ω) and is given by, WebbPSD的定义. PSD——Power Spectral Density 是表征信号的功率能量与频率的关系的物理量。. PSD经常用来研究随机振动信号。. PSD通常根据频率分辨率做归一化。. 对于振动数据,PSD的单位通常是g^2/Hz。. 这个单位看起来不很直观,但它有助于确保随机数据可以独立 …
