The (null) effect of spectral estimator on the estimation of spectral moments

The Journal of the Acoustical Society of America, 2013
The spectra of English voiceless sibilants [s] and [š], when computed with traditional estimators, such as the DFT calculated over an interval multiplied with a data window, exhibit relatively large variance, which is believed to introduce error in the estimation of linguistically meaningful features, such as the first four spectral moments (centroid ...

Spectral moment estimation by means of level crossings

Biometrika, 1974
Three types of estimator of the second spectral moment of a stationary Gaussian process are considered. The integral estimator is based on the integral of the squared derivative of the process, while crossing estimators make use of the number of upcrossings of zero or nonzero levels.

A spectral moment estimation problem in two dimensions

Biometrika, 1977
SUMMARY The estimation is considered of a certain function of the second-order spectral moments of a Gaussian process whose 'time' parameter lies in the plane. Two types of estimate are considered, both based on the level crossings of the process. The first is applicable when the values of the process are recorded continuously over the plane, the ...

Combinatorial methods for spectroscopic averaging and spectral moments

Physics Letters, 1966
Abstract The scalar and fixed-partition scalar averagings of an operator are treated by combinatorial methods which exploit the fact that the averages are polynomials in occupation numbers. The results are of particular value for studying the low-order moments of spectral distributions.
