Spectral domain sampling of graph signals
WebSpectral-domain models are probabilistic models that produce an estimate of the expected response of the WEC, for example, the expected average power capture. Spectral-domain … WebApr 13, 2024 · It should be noted how both the signal and noise are spectrally broadened to ≈4 nm as a result of the sampling process. In the temporal domain, it was clearly seen how the POD output was a sampled version (17.1 GSa s − 1 $\text{17.1\ GSa}\; {\text{s}}^{{-1}}$) of the input SUT.
