order curves The high power density curves in a spectral map which indicate order
components.
orthogonal-like Gabor
transform pair
The pair is composed of a Gabor transform and a Gabor expansion when
the Gabor coefficients cm, n found by each method are the projection of the
signal on the synthesis window function h[k].
over sampling Occurs in a Gabor transform when the window length is greater than the
window shift step. In over sampling, the number of Gabor coefficients cm, n
is more than the number of original data samples s[k].
R
resampling A method to sample a time sequence at a different time interval.
RMS Root mean square.
RPM Revolutions per minute.
S
STFT Short time Fourier transform.
W
window shift step The shortest time interval between two windows. In the LabVIEW Order
Analysis Toolset, it is always equal to a quarter (0.25) of the window
length. For example, if the window length is 2,048, the window shift is 512.
