As described above, BAO imparts a characteristic signal in the matter power spectrum on the scale of the sound horizon at recombination.
42.
The cirrus component can be identified in the power spectrum at low spatial frequencies and then removed from the whole spatial frequency range.
43.
The detailed analysis of CMBR data to produce maps, an angular power spectrum, and ultimately cosmological parameters is a complicated, computationally difficult problem.
44.
During this time he published two papers in 1959 about the power spectrum analysis of ozone and about vertical velocities in the lower stratosphere.
45.
Given the mean Doppler velocity ( mean frequency of the power spectrum ) of the measured volume along the line of sight-the radial velocity.
46.
Their primary goal was to measure the angular scale of the first acoustic peak of the anisotropies power spectrum, for which COBE had insufficient resolution.
47.
Deterministic processes present themselves as spikes on a power spectrum, whereas stochastic processes are broader i . e . spread over a wider frequency range.
48.
A Power spectrum can be calculated from a sequence of N _ f I _ n + iQ _ n components in the following way.
49.
The power spectrum SNR could not be calculated in the same manner as before because there were signal and noise components present at the same frequencies.
50.
If we assume that the wavelet is minimum phase, we can recover it by calculating the minimum phase equivalent of the power spectrum we just found.
