Secondly, HOS preserves phase information.
To preserve phase information, linear-phase filters that are nonorthogonal and in symmetric/anti-symmetric quadrature pairs should be used.
Shin et al. established a cross time-frequency transformation based on Williams' [21] definition that preserves phase information [22].
Higher-order statistics (HOS) are well known for their robustness to additive Gaussian noise and ability to preserve phase.
The symplectic tracking model can preserve phase space structure and reduce non-physical effects in long term simulation, which is important for beam property evaluation in particle accelerators.
We examine the implications of preserving the MS structure under discretization on the numerical scheme's ability to preserve phase space structure, as measured by the nonlinear spectrum of the governing equation.
The autocovariance of activity was used to distinguish limit cycles and quasi-cycles in ecological models by Pineda-Krch et al [27], since limit cycles preserve phase information better than quasi-cycles.
A bulkier head group (D12/3), which combines the glycerol moiety with an (EO 3 spacer unit, preserves phase separation into domains, but removes the strict symmetry, resulting in boomerang-shaped domains.
From this point of view, parametric amplifiers may be divided into two groups; phase sensitive amplifiers which amplify only one of the incoming quadratures, and phase insensitive amplifiers which amplify both quadratures, thereby preserving the phase of the signal.
