The Power Spectral DensityELSEVIEREssentials of Vehicle Dynamics
Chapter 3 details a unified approach, based on Fourier theory and a single definition, for defining the power spectral density of single waveforms, periodic signals, random processes, and over both the finite and infinite intervals. The approach is both straightforward and rigorous....

更确切的说,噪声波形x(t)的PSD,即SX(f),被定义为f附近1Hz带宽内x(t)具有的平均功率。 B. Power spectral density (PSD): the spectrum shows how much power the signal carries at each frequency, written as Sx(f). C. 相关知识点: 试题来源: 解析 A.nswer:(书)表示在每个频率上信号具有的功率...
In this paper we consider the power spectral density or power spectrum of temporal variations in atmospheric temperature on time scales of 10−2 to 106 yr. We will show that at frequencies smaller than f≈1/(40 ka) the power spectrum is flat (white noise). At frequencies between f≈1/...

Expressions are developed for the power spectral density (PSD) of a pulsed ultra wide band (UWB) signal for which the pulse repetition frequency (PRF) is directly modulated by a known time function. Parallels are drawn to the analog frequency-modulation (FM) case. An example for the swept-...
In this paper, the power spectral density of the wind speed which varies with height is given according to the field measurement of typhoon in Shanghai area. 文章根据上海地区台风的实测资料,提出了沿高度变化的风速功率谱密度,并应用随机振动理论,计算了上海电视塔在台风作用下的风致响应,取得了与实测...
