The spectral correlation density (SCD), sometimes also called the cyclic spectral density or spectral correlation function, is a function that describes the cross-spectral density of all pairs of frequency-shifted versions of a time-series.
The spectral correlation density applies only to cyclostationary processes because stationary processes do not exhibit spectral correlation. In ODS Correlation, an SDI value is calculated for each frequency sample in the band over which two blocks of measurements are compared.
An example is shown in Fig-ure 4.

Blurring is a form of bandwidth reduction of an ideal image owing to the imperfect image formation process. It can be caused by relative motion between the camera and the.
The Spectral Correlation Function (SCF) Project should give us a better understanding of what these data mean.
In a nutshell, the SCF compares observations of the distribution of velocities of gas particles in space, and it can be used to compare the observed distributions with theoretically prediced ones. This is normally a measurement with no sample in the beam.
This can be compared to the measurement with the sample in the beam to determine the “percent transmittance.” This technique results in a spectrum which has all of the instrumental characteristics removed.
Thus, all spectral features which are present are strictly due to the sample. AFile Size: 1MB. Abstract High-resolution crystal spectrometer measurements of the Kβ spectrum of heliumlike Ar 16+ covering the wavelength region from to Å are presented and compared with detailed theoretical analyses.

Spectral methods are a class of techniques used in applied mathematics and scientific computing to numerically solve certain differential equations, potentially involving the use of the fast Fourier idea is to write the solution of the differential equation as a sum of certain "basis functions" (for example, as a Fourier series which is a sum of sinusoids) and then to choose the.
