a Time-domain representation of the THz signal reflected from a single-layer PET foil with a nominal thickness of 23 µm (blue) and corresponding model function (orange) used for thickness determination. Details on the model function can be found in the “Methods” section. b Spectral amp...
Empirical Orthogonal Representation Of Time Series In The Frequency Domain. Part Ii: Application To The Study Of Tropical Wave Disturbances 来自 ResearchGate 喜欢 0 阅读量: 59 作者: JM Wallace 摘要: Rawinsonde data from the western Pacific region for the summer of 1967 are expanded in terms of...
Filtering is an important application of the Fourier transform. The Fourier representation of signals and the eigenfunction property of LTI systems provide the tools to change the frequency content of a signal by processing it with a LTI system with a desired frequency response. The idea of changin...
A detailed survey of the damage observed inside and outside of the structure was carried out in June 2017, within the context of ReLUIS project activities (Cattari et al.2019). The interested reader may refer to Degli Abbati et al. (2021) for a detailed representation of the cracking patt...

In order to recover an estimate of the original signal from the samples, the Fourier domain representation 6is multiplied by a rectangle function to extract one repetition of the repeated transforms. (It is also scaled by to recover the original amplitude.) The rectangle function, also shown in...
Signal waveform is the basic physical layer element that fundamentally determines the most important key performance indicator in communication systems, namely spectral efficiency. Traditional waveforms rely on orthogonal Nyquist shaping but result in re
CWT offers a high-resolution representation of the time–frequency domain by using near-continuous discretization. Its continuous time and frequency scales better support intricate time–frequency analysis. Consequently, CWT is often described as the mathematical microscope of data analysis10 (Fig. 2)....
